Why hasn't Justin Houston had a sack yet? He was supposed to be this stud pass rusher, and looked like it in the preseason. But now he's starting over a veteran Andy Studebaker and I haven't seen any reason on the field that that's a justified move. I know he's a rookie, but he was also supposed to be first round talent. Akeem Ayers, the prospect many of us wanted, already has a sack. Where is Houston's?
