What actually wins Best Ball Mania? I reverse-engineered every BBM champion from Underdog's official pick-by-pick data and found the same fingerprints on almost every winner. Here are the 5 truths every champion shared — with the receipts.

1) An elite advance-rate anchor. Every champ had at least one 28%+ player — JSN 39.6% ('25), Ja'Marr Chase 50% / Burrow 39.6% ('24), CeeDee Lamb 34.6% / Mostert 42.6% ('23), Tyler Lockett exactly 28% ('22), Jonathan Taylor 43% ('21). Most came in the first four rounds — you have to hit early.

2) Mid-to-late-round value in bulk. Every team stacked value late — Kyren Williams 15 rounds of value in Round 18, Mostert 12 in Round 13, Chase Brown 6, Chris Olave paying off 2nd-round value from Round 6. Titles are built in the back half of the draft.

3) Zeros don't kill you. 4 of 5 champs carried 2+ players who never hit the lineup (Renfrow — a 7th-rounder!, Sony Michel, Ty Chandler, Adam Thielen). Only 2023 had zero zeros. Don't fear the contingent handcuff.

4) Regular-season duds become playoff heroes. Brock Purdy 12% reg-season advance → must-have in Weeks 16 & 17. Jonathan Taylor 11% → 36% Week 16. Amari Cooper 11% → dropped 46 in Week 16. Tom Brady 8%. The guys who limped through the year won the chip.

5) Teammate stacks in the playoffs. Across all 5 winners, only ONE playoff week lacked a 2+ teammate stack (2023 Wk16). The 2024 Bengals stack — 4 in Wk15, 2 in Wk16, 3 in Wk17 — carried the whole run. Stack 2–4, QB optional.

The big takeaway: hunt outliers in BOTH phases — a regular-season stud to get you in, plus low-owned playoff heroes to win the single-week shootouts. Small miss, big hit.
