Fuller warned that Mayfield’s QB5, career-best 2024 season (highs in YPA, TDs, completion rate, and rushing yards) is unlikely to repeat. The Buccaneers lost OC Liam Coen—whom Fuller credits for the breakout—to Jacksonville, replacing him with first-time play-caller Josh Grizzard. Even with a deep WR room and pass-catching backs, Fuller expects natural regression in Mayfield’s efficiency metrics and believes the scheme change widens his downside range. Despite that, Mayfield is still being drafted in the QB7-QB10 window, leaving ample room to disappoint if his TD rate or yardage slide back toward career norms.
