Ineffective play by linemen and the Donte Whitner interception. If this was a home game, you bet your ass that would have been over turned. Instead, it allowed for three more points that ultimately decided the game.
Another side note, with something like 13:00 left in the fourth quarter after a Bills player was pushed out of bounds, the clock continued to run and ended up shaving off fourty seconds, that in a game like this were very important fractions of time. Anybody who Tivo'd the game, look back and you will see i am not smoking crack.
