I've always thought the player most like Curtis Martin in the college game was Ray Rice, mainly because of the vision that each had (Martin, arguably the best vision of any RB ever in my opinion, and Rice easily the best in the college game). Though, I definitely see the comparison to Hart, both are the type of back that will get positive yardage no matter what, both pretty agile, without the top end speed.
