Bucs offensive coordinator Liam Coen describes Baker Mayfield as an ignitor who'll move the running game forward. Coen plans to change run game strategies this season, putting more responsibility on Mayfield. Mayfield's high football I.Q., playing experience, and role in directing plays will be crucial. Zyon McCollum steps up, replacing Carlton Davis in a significant trade with the Lions. Cade Otton impresses, but the Bucs seek additional support to maintain his performance.
