text: As far as their rookie seasons are concerned, I'd say A.J. Hawk.  Bush will share carries with Deuce Mcallister.  Leinart will probably stay on the bench for at least the first 8 games.  If he starts, he'll suck like most rookie QBs.  Williams will - like most DEs in the 3-4 scheme - probably get stuck taking on tackles so the Texans linebackers can make plays.  I don't expect eye-popping stats from him.  Hawk, however, is practically a guaranteed starter at a position that traditionally racks up the tackles.
