I am in no way defending Costa's play last year, nor do I feel comfortable going into this year with him as the starter. With that said, how much effect does guard play have on the center? Last year, the guard positions were turnstiles, how many different guards did we have play last year? The offensive line is the most rhythmic position group in the game. Guys have to develop chemistry. Again, I am not excusing Costa's awful play last year. I hate the idea of him starting. However, I am curious to see what kind of effect it will have on his game if our guards remain healthy and could manage to play above average. From my limited knowledge of the center position (I played LT in HS), I believe the Center typically doubles up on a DT with a guard. I would perhaps be willing to -from a fan perspective, not a coaches- give the guy another chance and just see if he does any better. I guess I just don't want to give up on the guy just yet. I suppose we'll find out come game 1 against the Giants. Now that I mention it, what a great test for our offensive line to begin the season; keeping Tony upright against the Super Bowl Giants D-Line.
