Can it be true that Hoke and staff were so bad at talent evaluation that Miller is actually the 3rd or 4th best option at center and not the first? Or is Harbaugh's OL system so different that someone like Miller just doesn't fit and knows enough to walk away after 4 practices? Miller was a hard worker, it's not that he can't hack it and comments to that effect seem uncalled for. I can't figure this one out.
