Butch Barry needs to go. I don't know why we keep trotting Zion Nelson out there. He's clearly not ready. It's true the OL lacks talent, but it's also poorly coached. Technique is awful, poor communication, free rushers happen more than it should. Barry is doing the worst possible job he can even with limited talent to work with.
With that said, Enos playcalling does the OL absolutely no favors. The play action passes in obvious passing situations gives the defense an edge. Going under center instead of starting the QB in the gun hurts. Any time he goes I-formation, double tight or brings the WRs close to the tackle box hurts also. He brings more defenders inside the box making it harder to identify potential blitzers.
My recommendations are pretty much what everyone else has said in here in some way: fire Butch Barry, Fire Enos, go spread
