Gainwell gives the Bucs a receiving-minded complement rather than a redundant backup. He can stress linebackers on option routes and keep the offense flexible while Irving handles plenty of the core rushing workload.
Strengths: 1,000-plus scrimmage yards, 70 catches, option-route feel, and a clear top-two back role.
Weaknesses: Still likely shares touches with Irving and must keep pass protection sharp to stay on the field in high-leverage downs.
