Sorry man, but as a Packer fan, he's terrible and has been terrible. Having the best QB in the league hides just how awful he is. He was basically a decent offensive coordinator in New Orleans and helped San Francisco finish dead last in points scored during his one season as offensive coordinator there.
Can't say I watch GB close enough to know that aspect of McCarthy. He's never struck me as one of these conservative neanderthal coaches, but I guess it would take someone who watches every game, every play to know that, and he certainly coached like it in this game.
