‘O-Line continuity: There could be changes, but if there are not major ones, Buffalo will have a good chemistry at their offensive line. Dion Dawkins will return at tackle and Eric Wood will at center. At left guard, Richie Incognito is still under contract for next year, but his off-field issues and contract make him a question mark. Cordy Glenn can play opposite of Dawkins at tackle. Right guard might not even need an upgrade. Vlad Ducasse played a majority of games for the Bills, replacing John Miller. It appeared Miller struggled in a zone scheme but he previously thrived in the power scheme. Plug and go there and the Bills offensive line could have a strong chemistry. A quarterback is not going to mad about that.’
