I think WVU did zone blocking those years with Slaton (i could be wrong I will ask my boss since he is a die hard WVU guy) and that allows your offensive line to get a little more depth down field and open lanes. We don't do that and the offensive line's push is a big thing when facing a 8 man front and I think that had a lot to do with it. In fairness I think we are short in talent in a lot of areas and it really hurts the play calling but if you know that going into the season I think it then falls on the staff to find a system that fits the players. I hate the veer option but if our line can't get a push it might be the way to go.
They definitely zone blocked under trickett. I think that's his calling card. Good running teams face 8-man fronts quite often though. It's conventional wisdom to pass vs. this front but good running teams simply continue to run the ball.
