The gruesome knee injury Chubb suffered on national television at Georgia as a sophomore still casts a shadow over his resume, but the 5-11, 227-pound power back proved the last two seasons that he still has plenty to offer an NFL club even if he doesn't quite have the same explosiveness he once did. Chubb's low center of gravity, pad level and outstanding balance allow him to plow through traffic and pick up yards after contact, so he could be a goal-line weapon in the pros. He doesn't have breakaway speed and hasn't shown much ability as a receiver, however, likely limiting his role to early downs and short yardage. Drafted 35th overall, he joins a crowded backfield that also has receiving specialist Duke Johnson and former 49ers lead back Carlos Hyde - a situation that likely will limit Chubb's touches as a rookie unless he significantly outplays Hyde. Chubb did show a great deal of improvement between his final two years at Georgia, and if he makes another leap heading into 2018 and regains more of the burst and quick-cut ability he flashed prior to his injury, he could push Hyde right out of the picture.
