Stacking Frequency Study
Stacking Study — Regular Season
Which teammate stacks actually got you into the playoffs? Reconstructed from every entry in the field (2021–2025, ~2.5M teams), here’s the true advance rate of every specific combo — the exact 2, 3 and 4-player groups whose owners made the playoffs at well above the 16.7% baseline, with where each piece was drafted, what he scored, and how rare the stack was to own. For the “once you’re in, which stacks win playoff weeks” view, see the Postseason Stacking Study.
The outlier stacks — the combos that made the playoffs
Every specific teammate combo (2–4 players, any positions — QB optional) whose owners made the playoffs at 30%+ — nearly double the 16.7% field baseline or better. The one guardrail: the stack must have added advance rate — it beat its best single player alone, so the extra teammate helped rather than dragged. A cheap, below‑market piece is welcome as long as the combo beat its anchor — that’s the correlation edge. Every combo shown was actually co-drafted by 300+ real teams (see ownership), so it was always possible to roster together. Grouped by team, ranked by advance rate — the combos that made the playoffs on the left, the worst of the worst on the right. Click a team to expand every stack. Each rate is also a ×field multiple.
Advance rate = share of the combo’s owners that made the playoffs (out of the 14-week regular season). Only combos rostered by 300+ teams are shown so the rate is stable. Player ADP is the true Underdog BBM draft slot (round.pick); ownership = share of the whole field that drafted exactly that combo.
A stack = a team’s top 2–4 scorers in a week who each had a real game — no dead weight, so one guy at 50 and another at 10 never counts. Elite: every player cleared a startable line (QB 20 · RB/WR 15 · TE 11) and the group combined for 50+ / 70+ / 85+ (2 / 3 / 4‑stack). Maniacal is stricter — every player individually smashed (QB 28 · RB/WR 22 · TE 17) and combined for 65+ / 92+ / 110+.
Position Combinations
Most common position groupings that show up at this tier.
By Season
How many of each tier happened per season since the analysis window opened.
Position-Rank Combinations
Same tier × size selection as above, but broken down by who the players actually were. WR1 = the team's top WR by total season fantasy points (4-game minimum). Unranked players show as WR?. Use this to see whether maniacal stacks come from the obvious QB1 + WR1 pairing — or from sneaky QB1 + WR2 / WR3 combos.
Game Correlation — Both Teams Exploded
Games where BOTH offenses produced a qualifying stack (Elite or better) the same week — a correlated shootout. Lower of the two tiers defines the bucket. Use it to spot the matchups where stacking one side and running it back on the other both paid off.
