It was expected to see him ratings to go down against the better defenses. It is also expected to see his ratings go down when Pay, Keim, and Lapuapo got hurt. Mitchell did a good job as the back up center, but that took away from the depth at the other spots that he was playing in, and other players had to play out of position. It affected our running game and gave him less time. Losing Keim was as bad as losing Pay, if not worse.
