re: Hiliard will rush for over 1500 yards

If he was the feature back in the "committee" then yes he would easily go over 1000, I would say between 1150 and 1300 yards. Ware had 177 carries last year which is about 50 more than the #2. He also only had 33 carries over his last 5 games and he missed a game.

177/13(games played) = 13 carries a game.
144/7(games before ssp and Bama game)= 20 carries a game

Miles still has a feature back even if he runs by committee.

I'd say if Hilliard was the feature, he'd get about 18 carries because he's also a power back which you use in goaline and 3rd & 4th short yardage situations.

18x5.2(his ypc last year)= 93.6 yds a game
Over the course of 13 games would give you 1216.8yds

As the featured back, I could easily see him with 1200yds and 16 TDs.
