Damn it. What a complete idiot.
Urban has a pretty good history of being able to circle the wagons and turn this into a rallying point for the players who WILL be playing. And Dunlap's replacement, Justin Trattou, is a future NFL player in his own right. It's not the same as Dunlap, but the D is still very strong.
But, man: What an idiot Dunlap is. I'm sure he feels worse about this than anyone.
