3. Alvin Kamara
Kamara was a consensus four-star recruit out of Norcross, Ga. He has yet to fill out his 5-foot-10 frame, weighing only 195 pounds. While Kamara scores high on intangibles like field vision and projects to be a productive SEC running back with 4.55 40-yard-dash speed, it is unlikely that he will make a big impact this season. He needs more time in the Alabama weight room.
