IMO, it would depend how good the sex is. If she consistently gives good head, such as deep throating, and not just treating it like a lollipop, initiates it without being asked, and then swallows every time, then she is a keeper, and it is worth the small sacrifice. It's not like he has to totally miss the game either. Watching it on DVR is even better anyway IMO. FF through all the gawd damn, repetitive, mind numbing, intelligence insulting commercials, and MNF has more than it's share.
