Bills rookie QB Nathan Peterman played well for Buffalo, while their ground game impressed even without RB LeSean McCoy. Two late scoring passes from Lions rookie QB Brad Kaaya pushed the score to a respectable 27-17, however three turnovers proved too much to overcome for Detroit as they fell to Buffalo.

The final preseason game came, and went for the Lions and Bills, and with that, we give you our PFF exclusive takeaways from the contest for each team.
