San Francisco 49ers QB Blaine Gabbert has impressed new head coach Chip Kelly with his athleticism in offseason workouts. ‘He’s extremely athletic,’ Kelly began. ‘It’s interesting, the three of them, if you look at Driskel, Blaine and Kap, they’re all 6-4 plus, and all can run. All of them are at 4.6 (seconds in the 40-yard dash) or under 4.6, which is kind of rare to have three guys that can do the same thing. It’s beneficial to you.’
