Underdog Tips
Feeling like I’ve woken up from a nap that lasted far too long, this article is being written the same way I’ve enjoyed most things in my life - quick and messy. Hopefully, next year I can get back to writing the same epics for Underdog as I have in previous years. Much of my approach has remained the same from previous years, which you can review here: https://www.southharmonff.com/articles/category/The+Underdog+Series

Below, I have listed all the major updates I made for the 2025 Underdog campaign.
Hits & Misses
The foundation of my process is laboring through every Hit and Miss from my 2024 Rankings and writing out exactly what went right or wrong for each player. What constitutes a Hit or Miss, I discuss in last year’s series (see the above link). Using ChatGPT, I summarize the most common themes for each position. Once finished, I begin applying projections to players in 2025 that fit the descriptions of Hits and Misses from the previous two years. As a cornerstone for my rankings, I utilize the latest ADP of Underdog and update it manually as the off-season progresses. Listed below are the Top 2 Hits and Misses for each position:

Needle Movers
With my rankings moving in a good direction, it’s all micro-adjustments from here on out using numerous “Needle Movers.” These are categories that, through previous research by myself and many others, have been shown to have a significant correlation to fantasy production and provide an “edge” to the final rankings. I have listed ALL of my Needle Mover categories down below:
Vegas Projected Team Wins
Vegas Projected Team Points Scored
Vegas Projected Player Yards/TDs
Offensive Line Changes
Projected Breakouts
Underdog Trends & Tips
Top WoRP Players
Spike Weeks
Reception Perception Man Grades
Players Who Disappointed Last Year BUT Still In Prime AND Not Coming Off Injury (Oddly specific, I know)
Create a 2nd Ranking that includes AVG Ranks from Favorite Analysts (Look for biggest differences & adjust accordingly)
Final Touch = Flag Plants
Roster Construction
Listed below is the Roster Construction I aim for in every draft, based largely upon Hayden Wink’s Research from previous Best Ball Mania Tournaments. You can review his latest update here: https://underdognetwork.com/football/best-ball-research/what-has-worked-in-all-5-years-of-best-ball-mania
WRs
Get 3x by Rd 6, 4-5x by Rd 10, 6-7x by Rd 18
Total: 7-8x WRs (7x if 6 RBs or 3 QBs)
RBs
Get 2x by Rd 6, 4x by Rd 10, 5-6x by Rd
Total: 5-6x RBs (5x RBs if get 3x QBs)
TEs
Get 0-1x by Rd 9, 3x by Rd 18
Total: 3x TEs (2x top 12, top 23 OR top 8, 18, 23 OR after 11th)
QBs
Get 1x by Rd 14, wait on 2nd until after Rd 8, 3rd after Rd 15
Total: 2-3x QBs (DON'T get 2x top 5: 2x top 8 OR top 11, 16, 25)
Strategy
With so many amazing players (especially in the first two rounds), I am entering the 2025 season with a heavy emphasis on having a diverse portfolio. To achieve this, I am employing a new strategy in which I:
Move up player 1 Spot every 2 drafts I don't get a share of them
After Drafting Player, Drop them 1 Spot in Rds 1-9, 2 Spots in Rds 10-18
Draft only 2 shares of the Final selected QB, RB, WR, TE
Remove Players from Rankings after drafting 4-5 Shares of them
With 12 Best Ball Mania drafts on tap for 2025, and a Max 30-40% Exposure Rate for each player, the max number of shares I have allotted for my portfolio is four to five. This includes up to eight 3x-QB builds and up to four 2x-QB builds.
Best & Worst Playoff Projections
The final touch I use as a “tiebreaker” when on the clock and deciding between two players in the same tier is Playoff Projections for weeks 12-17 of the 2025 season. Using 2024’s Defensive Rushing and Passing EPA Per Play ranks, I assign a score to each player based on their defensive matchup. I have sourced these Defensive EPA Ranks from the Summer Series that Brett Kollman and E.J. Snyder record every year on the Bootleg Football channel (it’s the best yearly series for all those who love football). Listed below are the Top-5 and Bottom-5 Playoff Projections by positional group:
Easiest
#1 - Seattle Seahawks Passers & Receivers
#2 - Atlanta Falcons Passers & Receivers
#3 (Tied) - New Orleans Passers & Receivers
#3 (Tied) - Tennessee Titans Passers & Receivers
#5 - New York Jets Running Backs
Toughest
#1 - Green Bay Packers Passers & Receivers
#2 - Las Vegas Raiders Running Backs
#3 - Dallas Cowboys Passers & Receivers
#4 - Los Angeles Chargers Passers & Receivers
#5 - Kansas City Chiefs Running Backs
The Dossier
Underdog 40,000
It is the 41st Millennium in the Solum Canis galaxy. For centuries the Emperor has sat upon a boisterous throne as the ruler of the Imperium, by the will of the gods. He leads a never-ending campaign, turning the galaxy into his arena where he presides over a tournament of endless chaos.
Part 1 - Review of 2023
The Imperium
It is the 41st Millennium in the Solum Canis galaxy. For centuries the Emperor has sat upon a boisterous throne as the ruler of the Imperium, by the will of the gods. He leads a never-ending campaign, turning the galaxy into his arena where he presides over a tournament of endless chaos.
At the Emperor’s right hand is seated the Council of Creation. They manifest his will through the hellbent expansion of the Imperium. But now, the Council serves as regents with unlimited power for an emperor who has lost his mind to madness. They control all legions throughout the galaxy, including the Enlisted Guard, the Data Harvesters, the Scouting Conclave, and the Furnace Brotherhood. This untold myriad of forces keeps every horror that gushes through from the galactic rim at bay. It is their sacred duty to wage war against the degenerate, the apostate, and the demonic.
Five years into this latest Tournament of Mania, a new season of war is fast approaching and the Council deliberates on how they will wage their upcoming offensive. But before your league can be mobilized, the previous year’s campaign must be carefully reviewed.
Pandemonium
Functioning as the brain for the Imperial Legion are the Data Harvesters. They are gatekeepers to secret knowledge and arm the Emperor’s forces with invaluable intel. Operating in Hives throughout the galaxy, their bodies are suspended by countless life support tubes and drains, including a canopy of neural lines directly farming raw data to their brains.
The following summary report is comprised of four major categories:
Hits, Misses, & Injuries by Round
ADP Inaccuracy by Round
Hits vs Misses by Position
ADP Inaccuracy by Position
A “Hit” is categorized by a player’s 2023 Underdog ADP aligning with their season finish within a particular threshold:
Over 65% of Underdog ADP (top 219 players) completely missed the mark.
More than 13% of the top 254 players missed 6 or more games due to injury.
The average discrepancy between a player’s Underdog ADP and their 2023 finish was 19.23 places. In other words, on average the top 219 players were drafted 19 spots early/late.
The hit rate surpassed 50% in only 3/21 rounds.
The poorest drafted position in 2023 was WR. They were on average drafted two rounds early.
The poorest round came at the end of the draft, where the average 18th-round player was drafted 23.79 spots early/late. WRs in this range were drafted an average of 38.04 spots late/early.
Those who fought in last year’s crusade were subjected to a cruel existence, where only a third of the Imperium’s forces survived the evil Hordes. Will this intelligence prove worthy of the Council’s plans for the upcoming campaign? In a universe of doom, can there be progress or understanding?
Abandon Hope
The Data Harvesters are one side of a double-edged sword for the Emperor. Steering the Imperium’s politics is the Scouting Conclave. As a royal priesthood gifted in prophecy, they discern the paths to victory and counsel the Emperor on galactic dangers. Their Tabernacles travel as bastions across the stars, spreading the Emperor’s propaganda and instilling fanaticism throughout the Legion’s ranks. In the darkness of their innermost shrines, the clerics keep vigil as they profess the Imperatoris Sacramenta - The Emperor’s Sacraments. By unrelenting faith, the Emperor’s Legions endure the gods’ testing and bear the sacred burdens.
But many have strayed from the path and fallen into foul corruption. Their purpose has become vile, their strength lecherous, and their souls damned. To protect the Emperor’s Legions, the Conclave warns of divine judgment across the Imperium:
Woe to those who scorn the Elite QB and WR
Woe to those who place too much faith in unknown assets
Woe to those who align themselves with vile offenses
Woe to those who chase after backups or low-ceiling players
Many QBs and RBs will have their days cut short, and the Imperium will be thrown into darkness
Therefore, pursue the elite QB duo, do not doubt a third QB, stand firm in the elite WR trio, consecrate all-powerful offenses, and devote yourself entirely to alphas
11th Place Finish - Too many swings at unknown assets
The Cursed Sector
Far from the light of the Emperor, a distress signal is received from the desolate system Mortuus Zona - The Dead Zone. In a sector plagued by unpredictable WoRP surges and anomalies beyond comprehension, it is a haven for the apostate, the demonic, and the degenerate. Vast and deadly, Imperium forces are completely cut off from any hope of aid in the grim dark. The distress signal’s origin is a derelict Tabernacle, likely caught in the maelstrom of a WoRP surge. Hidden aboard the vessel exists the most powerful weapon in the Legion’s arsenal, developed by the Furnace Brotherhood.
An ancient guild of master craftsmen, the Brotherhood supplies the imperial war machine with its most deadly tools. Operating in the remotest sectors of the galaxy, their work often remains a terrible secret. This includes a new age of WoRP Technology, powerful enough to harness the energy of surges and convert them into limitless powerplants for machinery and devastating weaponry against any threat. Without this technology, the nests of the Horde would continue to fester unchecked, and eventually spill into the Imperium with the force of a tidal wave.
Utilizing WoRP Tech, we can gather:
Outside of the RB #1, WRs rule the galaxy by a significant margin
The Top 4 QBs overshadow TEs before trading blows for the rest of the draft
The Call
The path to glory is wrought with blood and toil. Each misstep magnified a thousandfold in the Tournament of Mania. In the arena of chaos, whispers of doubt will echo, the aroma of death will choke, the weight of despair will crush, and the eyes of annihilation will forever follow. These enemies are no foes to be conquered in a distant world but rather the demons that wreak havoc within ourselves. Vanquish the nemesis within, quiet their mockery, ready yourself for war, and answer the call to VICTORY!

Underdog Drafts
The Allied evacuation of Dunkirk during WWII, King Leonidas’ Spartans at the Hot Gates, and the army of Rohan at the Battle of Helm’s Deep… these moments in history are a lazy Sunday afternoon compared to the odds faced in Underdog tournaments. In a Best Ball Mania IV contest that features 677,376 entrants on the battlefield, the only chance for survival is the most rigorous commitment to a tempered strategy.

The Allied evacuation of Dunkirk during WWII, King Leonidas’ Spartans at the Hot Gates, and the army of Rohan at the Battle of Helm’s Deep… these moments in history are a lazy Sunday afternoon compared to the odds faced in Underdog tournaments. In a Best Ball Mania IV contest that features 677,376 entrants on the battlefield, the only chance for survival is the most rigorous commitment to a tempered strategy. Do not be tempted to invest tens of thousands of dollars into building a data center outfitted with complex algorithms that draft for you - Mad Max didn’t use AI when he entered the Thunderdome and neither should you. Instead, we will focus on wielding a process trained by historical data, risk assessment, and the most powerful tools in the space. This path does not guarantee all of your teams will survive the first onslaught, nor your most promising 18th-round pick will save you in the eleventh hour. But rest assured there’s no greater confidence than harnessing a strategy that can adapt to any circumstance that was built with your own sweat and efforts. Let’s get into it.
WoRP Your Mind
We will begin by freeing your mind of everything you thought you knew about Underdog drafts. ADP would have us believe that WR and the elite QB have overtaken RB as the focal position of the format. At the writing of this article, 19 of the top 36 players are WRs, along with 4 QBs and 2 TEs, which leaves 11 RBs remaining in the top three rounds of ADP. But much like parents, ADP is something we ought to respect but not always something we need to follow. And in a tournament that rewards the most unique combination of players, it will actually be to your benefit to stand out from the crowd. But in order to separate ourselves to our benefit, we have to determine what the most valuable positions and players are given the scoring and roster format on Underdog. The single best method available to us in the space for determining production value is WoRP.
I had the privilege of interviewing one of the foremost authorities in the field of WoRP, Dr. Koopa, Director of the Mind Flayer Project at the Labs of South Harmon Institute of Technology. In his research, he explains:
“WoRP, or Wins over Replacement Player, is a singular metric you can use to compare the value of players in your fantasy league, even across positions. Rather than using PPG, which can be biased towards one position (QBs) or against another (TEs), WoRP normalizes against the fantasy points of the replacement player, aka the best player at that position who didn't make your lineup. This allows you to compare one player to another, even if they score drastically different numbers of points. Finally, the values between positions can change from league to league, and the tool adjusts to your specific league settings to show you where an edge exists that wouldn't exist in a more "standard" league. With these calculations, we thought we might start a chain reaction that would destroy the entire fantasy world...I believe we did.”
Koopa may or may not have said that last part, but what is undeniable and most compelling is that WoRP “allows you to compare one player to another, even if they score drastically different numbers of points.” So what does 2022’s WoRP reveal to us about Underdog?
I hope everyone has been drafting RBs because they are far from being dead. Underdog is a half-point per reception scored format, which gives RBs more than a fighter’s chance to be on equal footing with their WRs counterparts. Three of the top four players last year were RBs, but Christian McCaffrey is the only RB who is being drafted consistently in the top six of Underdog drafts. Workhorse and dual-threat RBs are going to win contestants a lot of money this year.
When sorted by WoRP per game, there are only 13 WRs that make it into the top 36 (compared to the 19 WRs found in ADP), only 1 TE (2 TEs in ADP), and a whopping 18 RBs (only 11 RBs in top 36 of ADP)! It would appear that QB is the only position that is being drafted appropriately on Underdog and yet they are still being taken at value compared to their WoRP.
When armed with this knowledge, participants can effectively navigate Underdog drafts by avoiding the landmines who are being drafted too far ahead of what they can truly offer and letting the real difference-makers fall to them (often past their true ADP in terms of WoRP).
The Last of Us Strategy
Having played Underdog since their first year, there are a number of key lessons I have learned over the last three seasons. The following section comprises the very pillars of my strategy. To your benefit, I will hold these core principles of mine up to the magnificent light of WoRP, as well as in the brilliance of Hayden Wink’s research at Underdog Network. We will begin with Roster Construction, which is very similar to Taco Bell in that the possible combinations are endless despite there only being 4 ingredients.
2-3 QBs (DON'T get 2x top 5) - Having 2 top 5 QBs sounds good in theory, but we have to remember that this is a 1QB format, not SuperFlex. Why draft a 2nd elite QB at an elite cost (top 3-4 rds) that is going to score nearly the same amount of points as your other elite QB? Hayden Winks would further add “It looks like when we hit on a QB, it's best to wait until this Round 9-12 range.1” In terms of WoRP, the top 4 QBs were all nearly identical in the value they offered. I am betting on the elite 4 becoming an elite 7-8, with the likes of Lamar Jackson, Trevor Lawrence, Justin Herbert, or Justin Fields rounding out the steep slope we saw from last year.
Drafting 3 QBs is a strategy I am willing to employ in about a third of my drafts for two simple reasons: 1) I can capture 1-2 more high-WoRP skill players with the picks I would have otherwise spent on elite QBs if I’m aiming for 2nd/3rd tier QBs. 2) There are a number of QBs that have top-10 potential that are being drafted far later. But despite these assumptions, it’s hard to ignore how much better the elite QBs were compared to the rest of the field. The ideal QB strategy is perhaps drafting a top 8 QB and a 2nd QB that offers elite potential at a later ADP. Hayden Winks’ research affirms the 2 QB over the 3 QB strategy when he writes “2022: Once again, QB3 teams closed the gap on QB2 teams in Round 12, but never eclipsed them at any point on average.2”
3 TEs - An epidemic more alarming than the effects of Brainworm that continues to pervade the entire fantasy football space is the mishandling of the Tight End position. But thanks to recent breakthroughs in research, we have discovered a vaccine to cure our rosters of Persistent Tight End Arousal Syndrome (PTEAS). The best way to treat tight ends in Underdogs drafts is to draft three of them and punt the position entirely unless you have the fortune of drafting Travis Kelce. He is the one and only TE who consistently challenges the top RBs and WRs in fantasy that is worth his 1st round value.
After Kelce the position plummets to an abysmal plane of existence that never once comes close to WRs or RBs. Given how flat the position is after TE 6 (Schultz = 0.032 WoRP/G) until TE 31 (Otton = 0.011 WoRP/G), there isn’t any upside to drafting a top 10-12 ADP tight end in the first 11 rounds of your Underdog drafts. It’s essential to draft 3 TEs given the absurd volatility of the position - Kelce registered a combined 20 Spike and Above Average weeks last season, while TEs 2-32 had an average 4.9 combined Spike and Above Average weeks in 2022. Woof.
5-6 RBs (5 RBs if you get 3 QBs) & 7-8 WRs (7 WRs if get 6 RBs or 3 QBs) - Knowing that 5-6 spots on your 17-player roster have already been spoken for by the QBs and TEs, this leaves 11-12 roster spots that can be devoted to the RB and WR position. There are a number of factors that play into drafting slightly more WRs than RBs, but the most significant is the starting lineups on Underdog (2 RBs, 3 WRs, 1 Flex) and the edge in WoRP that WR commands after a certain point in the draft. Before every draft, I take a “snapshot” of how the WoRP/G distributes between the various positions every 6 spots in the top WoRP players.
As you can see in the above Underdog snapshot, RB and WR trade superiority throughout the top 42 of their respective positions, with perhaps a slight advantage to RB. That edge quickly gives way to the WRs after the 42nd RB and is never regained. Bearing this dropoff at RB in mind, be diligent in drafting at least 3, but ideally 4, of these top 40ish RBs, and saving room for 1-2 upside dart throws for later in your drafts.
Furthermore, I would not recommend drafting more than two rookie WRs per roster given how long it typically takes for rookies to acclimate to the NFL. Lastly, I would not advocate for drafting too many Boom WRs towards the end of the draft whose game is entirely predicated on the big-play over the safe-floor veterans that are routinely available.
There Can Only Be One!
Much more can be said about what it takes to be the last one standing, but outside of what I’ve already shared from my personal findings, I would highly recommend checking out the following articles from Hayden Winks to help prepare for Underdog drafts. I’ll end it with one final piece of advice: don’t draft timid - It’s better to burn out than to fade away!
