His number of throws is inflated a bit. After the Bills fell behind in the fourth, after the fumble/TD, they had to play catch up. He threw it 16 times after that point. Which, if the game didn't get out of hand like that, I'm sure wouldn't of happen. And previous to that point, he wasn't being asked to carry the team. But when a team falls behind, a team unfortunately has to go to the air.
If you were watching the game the commentators even commented in the 3rd quarter how run heavy the Bills were, in comparison to the Chiefs.
