I doubt LJ, LT or SA are going to have the years they are used to having. This year, I think, it's going to be about the Gores, Ronnie Browns, Parkers, etc.
SA will do fine i think. He's never had a season with less than 14 TDs and always has had more than 1000 yds rushing (minus his rookie year). Once their O-Line adjusts w/out Hutchinson, SA will get the yds and TDs.
Big bust i think is LJ. Green might be out of commision for a while and LJ had an ok game.
