Defenses change from year to year, and while PItt should still be an upper tier D, we don't know for sure. Looks like they are down a starting LB this week, and when CJ faced them towards the end of last year he ran for 69 yards on 16 carries (4.3 avg) and had a TD.
Bush hasn't played all preseason, has been slowed by injuries, and I really think Bell is the benefactor of Pierre missing the game. Especially if the game goes as most thing, and the Saints get up in the game. I really think Bush gets rested any time the Saints have a chance. Go with CJ.
