I also was wondering why he was laughing there. I figured they were friends and I think one of them had a baby recently so they were discussing that or something, but I would have personally saved that stuff for later and been pissed there. But to each his own.
The sad part about that game was that if Pressure Pete just makes that simple field goal, all the myths about Gannon being a winner (he would have regressed the Raiders to 7-9) and Grbac being a loser (he would have won the division and hosted a playoff game) and Grbac not being able to deliver in an important game would have evaporated. And a Raider loss may have cost Gruden his job, depending on how Alice Davis felt after the game.
Damn kickers. They have screwed with the fate of this franchise so much...
