Underdog Playoff Best Ball Strategy: Draft To Survive
The NFL regular season ends in Week 18 and most fantasy leagues wrap even earlier, but Underdog Fantasy keeps drafting alive through February with Playoff Best Ball, an elimination contest played across the four playoff rounds that carried a $1.5 million prize pool in the version this guide is built on. Winning it takes a different skill than winning a September draft. Underdog playoff best ball strategy is not about picking the best players; it is about drafting NFL rosters that are still alive when the Super Bowl kicks off, and most entries die long before that.
The Quick Answer
Draft every playoff best ball roster with one vision in mind: the exact Super Bowl matchup you believe in. Stack one NFC team and one AFC team using a 5-5, 4-3-3, or 4-2-2-2 build, avoid rosters whose only quarterback sits out the Wild Card round, and make sure you can still field five live players in the final round. The full contest rules, the survival math on all three builds, and the bye-week trap that ends most entries early are below.

How Underdog Playoff Best Ball Works
Playoff best ball runs on the NFL postseason instead of the regular season. Entry fees have ranged from $5 up to a few hundred dollars per draft, with the flagship contest, The Gauntlet, running at $25 to enter against a $1.5 million prize pool the year Underdog scaled it up. You draft, and then the game plays itself: no waivers, no trades, no weekly lineup decisions.
The format in the flagship contest:
| Rule | Detail |
|---|---|
| Draft Size | 6 entrants per draft, snake order, 30-second pick clock |
| Roster | 10 players: 1 QB, 1 RB, 2 WR/TE, 1 flex, 5 bench |
| Scoring | Half-point PPR; each round your best scorer at every required slot (QB, RB, two WR/TE, flex) is auto-started |
| Rounds | Wild Card, Divisional, Conference Championship, Super Bowl |
| Points | Reset every round; only that round's score decides who advances |
Advancement is where the contest shows its teeth. Your 6-person draft group sends 2 entries through the Wild Card round. Survivors regroup into 14-person pods for the Divisional round, then 8-person pods for the Conference Championship, where only 1 of 8 moves on. Everyone left lands in a single 400-person group for the Super Bowl, and reaching that final room is where the money concentrates. The Conference Championship round is the choke point, and everything in this guide is ultimately about getting through that cut with enough live scorers to still matter in the final round. Contest sizes, the Divisional cut rate, and payouts shift from season to season, so read the current rules card on Underdog before your first draft.

Why The Payout Structure Changes How You Draft
The $1.5 million version paid $150,000 to first, $75,000 to second, and $55,000 to third. Compare that with contests that dangle a $1 million first prize out of a $2 million pool: half the money lands on one entry, and realistically that entry is not going to be yours. The flatter structure leaves the top three holding $280,000 of the $1.5 million, with the rest of the pool spread through the field instead of piled on one winner, and that changes the goal. You are not drafting to be the single best roster in the field; you are drafting to reach the final Super Bowl room, which Loughran calls the point where you are into some pretty significant money.
Chain the cuts together (1-in-3 out of your draft room, another cut in the Divisional pods, then 1-in-8) and any single entry reaches that room a small fraction of the time. A marginal live player in the final round is therefore worth more than a marginal point in the Wild Card round, and every strategy decision below follows from that trade: build correlated rosters that survive with enough live players to matter.
Draft Every Roster For One Super Bowl Matchup
The core of playoff best ball is telling yourself a story about February. Pick the AFC team you believe can reach the Super Bowl, pick the NFC team, and stack them: quarterback with his pass catchers and playmakers, the pieces that score together when the offense hits. Split your two stacks across conferences, always. Only one team per conference can reach the final round, so a same-conference build caps your ceiling at the size of your single biggest stack: go 5-5 on two AFC teams and your best case is exactly five live players with zero slack.
So which teams qualify as believable? Loughran's advice in the video is to study the playoff picture before drafting: each team's odds of making the field, its likely path, and the bye scenarios. We take that one step further with the betting market. Convert a team's Super Bowl futures price at books like DraftKings and FanDuel into an implied probability (+400 works out to roughly a 20% shot at the final, before vig) and rank your candidate stacks by it; a full futures board prices to well over 100%, so treat the raw number as a ranking tool rather than a true probability. Once the field is set, our live odds screen handles the game-by-game side, an odds comparison across 20+ sportsbooks on each playoff matchup, while the futures conversion above runs off the futures board at your book.
The draft room gives you openings when the field overreacts to late-season struggles. A talented team that stumbles down the stretch sees its players' average draft position (ADP) slip, because most drafters stop treating them as Super Bowl material. Still believe in the roster? That discount is exactly where you want to be heavy. An unlikely conference-title pairing is fine too: everyone in your pod is drafting the obvious contenders, and an off-the-board pairing is what separates you, both in your 6-person room and in the final field, where the survivors mostly made the same safe calls.

The Three Builds: A Worked Example In Survival Math
Roster construction is survival math. Here is how the three standard builds hold up if your read hits:
| Build | How It Splits | If Your Super Bowl Read Hits | Live Players In The Final |
|---|---|---|---|
| 5-5 | 5 from one NFC team, 5 from one AFC team | Both stacks reach the Super Bowl | 10 |
| 4-3-3 | 4 from one conference's team, 3 and 3 from two teams in the other | The 4-stack plus one 3-stack reach | 7 |
| 4-2-2-2 | 4 from your strongest read, 2-2-2 across the other conference | The 4-stack plus one 2-stack reach | 6 |
The 4-3-3 is the row we keep coming back to, because it shows what diversification actually buys. Say you take four players from your NFC team, then split the AFC side three and three across two contenders. If your NFC read reaches the Super Bowl alongside either AFC team, you carry 7 live players into the final round, needing only 5 to fill a lineup. You gave up the 10-player ceiling of the 5-5 to hold two separate AFC paths, so you can survive one of your two AFC reads missing. The 4-stack side carries no such insurance: if that team falls short, three live players cannot fill a five-man lineup and the build is dead, an asymmetry that applies double to the 4-2-2-2. The 5-5 is the highest ceiling and the thinnest margin: if either stack falls short, you are filling a Super Bowl lineup from a 5-player pool with zero slack, and one injury ends you.
Whatever the build, the test is the same one Loughran kept returning to: if you make the final round, can this roster still field five players who are alive? A team with 8 of its 10 players eliminated is dead weight in the one round where the money lives, no matter how well those players scored in January.
The Bye-Week Trap And Other Early Exits
The fastest way to lose is to never make it out of the Wild Card round, and rosters die there in predictable ways. The No. 1 seed in each conference sits out Wild Card weekend, and points reset every round, so a roster built around a bye team scores nothing from those players in the one round it must survive. The killer version of the mistake: your only quarterback plays for the top seed. Only 2 of 6 entries advance, and you are trying to do it with a zero at the highest-scoring position. If you love a bye team as your Super Bowl read, either accept the Wild Card risk consciously or add a second quarterback from a team playing that weekend. One quarterback is often the optimal allocation on a 10-man roster; a one-quarterback roster whose passer is idle in round one is a different thing entirely. Stacking two bye teams at once is the same trap doubled.
Timing your drafts carries a similar trade-off. Draft before the regular season ends and you get discounts on players the market has not caught up to, the same late-round value dynamic that pays off in season-long best ball. The cost is real: players get hurt, and a team you drafted heavily can miss the playoffs outright and torch the whole entry. Draft after the field is set and you get certainty, but the value is gone and everyone is working from the same bracket. Drafting early means tracking the playoff picture closely, especially which teams are likely to clinch the byes.
Scoring format matters at the margins too. Underdog's playoff contests have used half-point PPR, which nudges value toward high-volume pass catchers relative to standard scoring. Know the setting before you draft rather than after, the same discipline that applies on PrizePicks or Sleeper when a scoring quirk quietly changes who is worth rostering.

Frequently Asked Questions
What is playoff best ball on Underdog Fantasy? A draft-only NFL fantasy contest played over the four playoff rounds. You draft 10 players, your best scorer at each required position auto-starts every round, points reset every round, and entries advance through group cuts until a final Super Bowl group decides the big prizes.
How many teams should you stack in playoff best ball? Two to four, always covering both conferences. The 5-5 build maximizes your ceiling with one team from each side, while 4-3-3 and 4-2-2-2 trade ceiling for extra paths through the bracket. Put all ten players in one conference and your best case is exactly five live players in the final, with no margin for a single inactive.
Can you enter more than one playoff best ball draft? Yes. The contest is built around drafting as many rosters as your budget allows, and spreading different Super Bowl reads across separate entries beats betting everything on one pairing.
The Bottom Line
Underdog playoff best ball rewards one thing above all: rosters that are still breathing in the final round. Before you enter a draft, map the entry to a specific Super Bowl pairing and count its live-player paths, first for Wild Card weekend, then for the final. Every real decision in the format is a tradeoff against that count. One quarterback is usually the right allocation, unless that quarterback is idle on Wild Card weekend. Drafting early buys you ADP discounts on good teams that finished ugly, at the price of injury risk and the chance a stack misses the field entirely. A 5-5 build buys the highest ceiling at the price of zero slack; 4-3-3 and 4-2-2-2 buy insurance at the price of that ceiling. Weigh each one against the same test: can this roster still put five live players on the field in the last round? Clear the eight-person Conference Championship pods with the answer still yes, and you are in the room where the money is. After that, as Loughran put it, you pray to the football gods on injuries. The correlation you can control; February you cannot.
