What happened: Josh Allen enters his ninth NFL season as the Buffalo Bills' franchise quarterback after an overtime divisional-round loss to the Denver Broncos. Buffalo promoted Joe Brady to head coach, acquired receiver DJ Moore and signed pass rusher Bradley Chubb.

Why it matters: Moore's receiving yardage has declined from 1,364 to 966 to 682 across the past three seasons, making him a risky answer to Buffalo's biggest offensive need. Allen preserves the championship ceiling, but a coaching transition and a defense that has dipped over the past two seasons leave too many unresolved variables for third overall.
