Baker Mayfield or Bucky Irving: Who Should You Start?

The call

• Consensus has him at QB20, which sits outside the 12 starting jobs in a standard league — the projection says usable, the rank says bench if you roster a top-12 arm.
• A 23.5 implied team total is mid-range scoring environment; with the Bucs inside a 3.5-point spread, there's no blowout script forcing volume passing in either direction.
• Role is unquestioned — locked-in QB1 on the depth chart, no injury designation — so the 16.2 floor is real; he just needs the matchup to break right to clear QB1 value.
• Tip it toward start if your alternative is a sub-16-point QB or you need ceiling; sit him if you hold a top-12 option with a softer draw.

The call

• He's still Tampa Bay's lead back off a 62% snap share, and RB22 with a 12.4 projection is a legitimate low-end RB2/flex in 12-team PPR.
• The committee math is the problem: ESPN (2026-09-04) has Kenny Gainwell — 73 catches for Pittsburgh in 2025 — taking passing-situation work, which threatens the 11% target share that propped up his PPR floor, while Sean Tucker (seven rushing TDs last season) is expected to keep goal-line duty.
• A 23.5 implied team total and a 3.5-point spread point to a close, moderate-scoring game rather than the run-heavy blowout script that would make him a clear start.
• Tip it to start if Gainwell's third-down role is slow to materialize or Irving works near the goal line early; tip it to sit if you roster a back with unchallenged receiving and red-zone work.
