I think a healthy Helu will still be the number 1 back. His burst through the hole and ability to cut without losing speed is astounding. Rex however will take all the snaps at our "wild-husker" or whatever you want to name it. Depending on the progress of our QBs I could see Helu getting 17-20 carries a game, Burkhead getting 10-13 carries and Robinson/Heard getting 5 or 6 carries a game.
