Izzy may have single handedly won us that game.
Say what you will about Jennings making the pick which helped us seal up the game, the game saving/winning play came much earlier.
Think about this, both team scored three TDs, and nothing else.
The difference is, Izzy blocked the extra point for the Bills, and they missed the 2 pointer on their final score of the game.
Bears scored three TDs as well, and a 2 pointer on their final TDs of the game.
If the Bills had not of missed the extra point, there would be no need to go for two on the following TD, and they would have had 21 points.
Bears would not have gone for two if the Bills had not of had their extra point blocked, because it would not have made sense.
With the Bills at 19 and Bears at 20, they needed the 2 pointer to make sure a field goal would not beat them. If the Bills had 21, bears would have just kicked the extra point.
I doubt how the rest of the game played out would have changed, because the ball was never turned over, and the Bills just had to kick off.
Game would have likely gone into overtime (third week in a row for the Bills) where anything could happen.
That is why I say Izzy won us the game!
