Well this year he has legitimate NFL talent at C. That's big. He also has a more mature and experienced Tyron Smith at LT. That should help too. I expect improvement. Won't be good enough, but improvement. What I pointed out was if Hudson Houck was a washed up coach and Bill Callahan is a huge upgrade we should have seen some semblance of improved play from our OL last year. From somebody. We didn't. Because the OL coach has zero to do with why our OL has struggled in recent years. I don't doubt Bill Callahan can coach a good OL. He's done it in the past. When he had better personnel.
