Harris is a different kind of back than Lewis. Lewis could be a great complimentary back, good receiver out of the backfield, and a kick returner, had a ton of moves, escapability. Harris is a #1 back, that's what he needs to be effective, to get 15-20 carries a game. But he certainly has proven to be the real deal. Averaging 5.5 yards per carry is no joke. Though Cam is the short yardage, goal line RB. Burkhead is pretty decent at goal line as well. Harris and Burkhead run HARD, I love that, tough to defend.
