Definitely NOT Hasselbeck after what PWillie did to him.
I like Garrard more in a vaccuum, but I think that the matchup that Campbell has this week is more favorable. Points are always scored against Detroit, so go with Campbell and hope that he does some of the scoring in the redzone.
Definitely go with Campbell. Hasselbeck will be out more likely than not, and if he does play he wont be worth a damn. JAX is going to be running the ball most of the time on HOU if they have half a brain. Campbell is the clear choice.
