I don't know what Glasgow's PFF grades have been, but he has felt like a weak link all year long. So I don't know, given his age and decline in play, that he would ever be clicking with this line. He's just a not that good a player at this stage on his career. It's why bringing back a Zeitler or getting a similar player in the offseason was wanted by many. That way a guy like Ratledge could have possibly taken snaps at Center or possibly rode the bench for part of the season while they tried Glasgow out.
