Weeks ago, an observer with connections in the Washington Redskins’ locker room described the heart murmur plaguing the club in the following way: “Ask yourself this: If Mike Shanahan wants to bench Robert Griffin III, can he?” The fact that there was even a doubt suggested the illness. Shanahan is now calling the question publicly, and he’s right to do so, because if he can’t bench Griffin, then he’s not really the head coach, and in fact no one will ever be Griffin’s coach, they’ll just be his concierges.
