Bear in mind that even had the Rams succeeded in a two-point conversion, the Patriots field goal still would have won the game.
That's all they needed to do when they had the ball and a 17-10 lead with 2:00 or so left. But they failed to get a single first down. The Rams had no time outs. A first down and 3 kneel downs and it's over.
When the Pats failed to get that first down and punted, my faith waivered. I knew the defense was dog tired and thought for sure this was headed for overtime. But the Rams' biggest mistake of the night turned out to be leaving 1:30 on the clock. I'll bet you dollars for donuts that the Rams were cock-sure that there was no way the Pats were going to be able to drive on them the way they did.
