The worst period ever for offensive line play? I completely agree.

Sometimes, ... it's like a pitcher. First time around, he can get people out, but then everybody's seen his stuff. He's got to mature, and it's the same thing with offensive linemen. If you don't mature in this league, you're in trouble.

I'm 38 years old, and it's flattering to get called by some personnel director, asking me if I want to come back. Once or twice, maybe, and it's kind of funny, but I'm hearing it all the time, from almost all of them. It's serious.

First of all, I don't think you develop real skills running the West Coast Offense.
