I have never been a McNabb fan, but "Grossman knows the 2 minute offense better" is one of the weirdest decisions/excuses I've ever heard especially from a Super Bowl Champion coach.
Especially since he completely boned it on the very first play he was in the game. McNabb had been throwing some weak passes, and did lose the game with the pick he shouldn't have thrown. The announcers were speculating that McNabb was injured because they couldn't think of any reason to bench him. With all the close games Detroit has had this year, I figured the Skins would be the ones to finally choke against them.
