The thing is... Case was EN FUEGO through the first three quarters... then he threw back to back TERRIBLE interceptions. Basically let the Redskins right back into a game that should have been on ice for the 4th quarter.
I was ready to say keep him in there for the foreseeable future, but those interceptions left the door wide open for Teddy IMO. I hate to criticize him because he played well overall and the Vikings won... but those interceptions aren't going to sit well with the coaching staff.
