Steven Jackson heads a deep class at runningback. With his combination of size, strength and speed, you'd think it a given that he is to become an elite NFL starter. However, there are enough questions about his maturity as an underclassman to leave a few dark marks on his record, that he is not a "can't-miss" type of prospect. That said, Jackson was highly productive during his sophomore and junior seasons, and his overall talent cannot be overlooked. He'll probably be the first running back taken, and could go in the top ten.
