Why does anyone care if he comes to Michigan? According to ESPN he isn't a homerun threat, he is a short, stocky power back, with quickness but lacking in speed. Isn't that what our backfield is full of now? He is what Vincent Smith was supposed to be, which supposedly is impressive but at leat Vincent used to be fast. I don't think he provides a great threat with Denard in the backfield. He is projected as more of a change of pace back...well read for yourself...this is what ESPN had to say.
Hart is a short, stocky runner with great quickness and productivity. A small explosive package. Utilizes his low center of gravity to his advantage as a runner; very difficult to get direct shot on him. Hits the hole with great downhill burst and authority. A decisive runner. Can slice back through the small cutback seams. Shows good lateral quickness and vision stretching it outside as well. Between the tackles he's difficult to wrap up cleanly. Runs with great lean and a powerful base. Absorbs the hit, keeps his balance and downhill momentum as good as any; like a pinball off tacklers at times. Runs hard and is a determined back who can move the pile and spin out of it. While he flashes good speed and burst through the second level, he is a short-strider and a bit quicker than fast. More of a back who will rip off the 10-15 yard burst than a homerun threat. Strong, sturdy and shifty but his shorter frame does bring up durability concerns and he appears to have peaked physically and maybe overall as a runner. Projects more as a change-of-pace runner who could come in and shred a tired defense with his great speed-to-power running style. Has polished hands out of the backfield to help get him more touches without having to carry the load. Overall, Hart is a great competitor and running back prospect who would be garnering more national attention if he just had a few extra inches.
Sounds like more of a Mike Hart...than a read option, td on any possession kinda guy to me.
