Underdog Best Ball Draft Strategy: Approaching Best Ball Mania in 2026

Here's a sentence I never get tired of typing: Best Ball Mania is back.

Underdog's flagship $25 best ball contest (the one that generally has a $2-$3 million first-place bounty and enough total prize money sloshing around to fund a small nation) opens its doors on Monday, April 28th. And if you've been grinding the Big Board all spring the way we have, you already know this is the moment we've been building toward.

Before we get into strategy, I want to address one debate that pops up every year: Does it actually matter when you draft your BBM entries?

This is an important question because Best Ball Mania is open for nearly 4.5 months, which represents a super long drafting window with pros and cons to drafting at any specific time.

The short answer is no. The perfect team can be built at any point over the summer. Some of the best BBM teams in history were drafted right in the middle of the summer, and some were drafted at the very end.

That said, there are very real strategic advantages to being among the first through the door on Monday. And there is an edge available right now that won't exist for much longer.

Best Ball Mania Underdog Draft Strategy Tips for 2026

The Closing Line Value Window

In the days immediately following the NFL Draft, the fantasy football ADP market is at its most inefficient. A huge chunk of rookie ADP is still being pulled from pre-draft contests that have no idea where any of these players are going to land. That information gap is what we are trying to exploit when the contest opens.

If you are curious why CLV is important, Michael Leone's BBM3 research quantified just how much it matters. The top 10% of teams gained ADP value equivalent to 116 picks, while the bottom 10% gave up the equivalent of 212 picks. The gap between the best and worst drafters is 328 picks. That's not noise.

The overwhelming majority of that edge is built in the early days of the contest, before the market self-corrects. So every day you wait, the window for accruing giant CLV closes.

Rookie CLV Chasing

Our best chance for CLV this year will come in the form of rookies and specifically the WRs who are currently priced well below where their projected NFL draft capital.

There is a well-established pattern in best ball: rookie WRs drafted in Round 1 of the NFL Draft become top-90 selections by the end of the summer. There have only been a few exceptions over the past three years.

Based on our most recent NFL mock drafts, three WRs beyond the top tier are projected to go Round 1: Omar Cooper Jr. (ADP: 128.7), Denzel Boston (ADP: 142.0) and KC Concepcion (ADP: 110.7). If those ADPs and draft capital hold, all three are being handed to you at a major discount right now. Cooper, in particular, has been creeping into top-20 territory in recent mocks. His current ADP is a gift.

The same thought process can be applied to the Round 2 WRs. Chris Brazzell II (ADP: 201), Germie Bernard (ADP: 202), Zachariah Branch (ADP: 220) and Chris Bell (ADP: 229) are all projected Round 2 picks currently going in the 17th round or later.

The moment the NFL Draft confirms their landing spots, these prices are going up. Not all of them will hit, and that's fine. You're not paying for certainty. You're paying pennies on the dollar for optionality that is all but guaranteed to appreciate.

The goal is simple: build teams with players at prices that won't exist in two weeks. You're pulling the ladder up behind you and drafting in an environment that later drafters won't have access to.

Avoiding Fallers Is Just As Important

There's an old adage on Underdog that risers never rise fast enough and fallers never fall fast enough. This is because ADP is sticky. People anchor to pre-draft prices and can get tricked into thinking a player is a value if he slips a round past ADP, but if a player's true new value is two rounds past ADP, that's a fugazi value. You're not getting a deal. You're buying a landmine.

The reason ADP takes so long to correct is also partly structural. Auto-drafters default to the top available pick by ADP, which means the true landmines get stepped on repeatedly before the market can catch up. A player whose situation cratered in the draft (bad landing spot, crowded depth chart, poor draft capital) will still get drafted at his old price far longer than he should.

The discipline to avoid those players is just as valuable as the aggression to target the risers.

Stack the Rookies With Their New Teammates

The other thing you can finally do when BBM opens is build real stacks. Pre-draft contests are guesswork. Now you know where everyone landed. Leone's research revealed that teams with 3-5 stacked players advanced at above-average rates in BBM.

Don't just scoop up the rookie WRs in isolation as we did in the Big Board; find the QBs they're going to play with and stack 'em up.

A Final Caveat On Early Best Ball Mania Drafting

The sad reality is that the drafting community has gotten dramatically sharper over the years. In the early BBM days, the opening of the contest was a gold rush. Early drafters were asleep at the wheel, and you could find massive CLV simply by showing up. Those days are gone.

Best ball has exploded in popularity, which means more and more sharp eyes are on the contest the moment it opens. Strategy articles will be published within hours of the first round completing. The values will be harder to come by, and they won't last nearly as long as they once did.

I still recommend getting some early drafts in because you only need to land in one perfect room for it to pay off, but don't overdo it. The downside to chasing CLV is that drafting early means drafting with incomplete information. Injuries happen. Depth charts shift. Training camp surprises emerge. The drafter who enters in late August has a significant informational advantage over you in ways that are impossible to fully account for right now. That gap is going to produce dead roster spots on your early teams, and that's just the cost of doing business.

Be aware of those tradeoffs when you're allocating your bankroll and deciding how many entries to fire. Like everything in life, balance is paramount. Move quickly, but move smart.
