It was a happy day to be the Buffalo Bills and Sean McDermott.

The Bills (11-3) topped the Detroit Lions (12-2) in a 48-42 final in Week 15. It was a battle between two of the best teams in the NFL and Buffalo came out on top.

Heading into the contest, the Bills were behind the eight ball since their practice schedule had been altered by weather.

Despite that, a win… and McDermott made sure to point that out during his locker room speech to his team after the final whistle.
