I never thought Butler was an adequate replacement for Winston, and nothing he's done has swayed that opinion. For all the times I complained about Winston getting eaten by a speed rusher, I knew he was better than Butler. And Antoine Caldwell has disappointed from the beginning. It took me a while to recognize, but he's never going to develop into a solid starting OL. I think Schaub can make them look decent in the passing game, because he generally gets the ball out pretty quick these days, but the cut back lanes for Foster are going to be iffy.
