ALL the skill positions changed that year, and it was Duece that carried the load at RB on that team.
Bush still moved the chains a lot on 3rd downs. He missed 4 games last year, and still had 74 receptions. Our offensive line was terrible in run blocking last year. Before Deuce was injured in the 3rd game, he wasn't even averaging 3.5 yds a carry.
Bush was not a bust in 2006. He gained over 1300+ yds total, and remember we had Deuce, Colston, Horn, Henderson, Stecker sharing the ball. Thats pretty good. Plus our offense is pass, pass, pass, pass, pass, run, pass, pass, pass. You get the point.
Don't base much off 2007. It was a bad year all around.
