GIF: Sean Smith’s 101-yard pick six against the Buffalo Bills

The Kansas City Chiefs entered Sunday’s game against the Buffalo Bills with a perfect 8-0 record. Buffalo, on the other hand, was sitting two games below .500 at 3-5.

If the Bills were going to have a chance against the brutally efficient Chiefs, backup quarterback Jeff Tuel was going to have to minimize his mistakes against an opportunistic defense.

That’s exactly the opposite of what Tuel did deep in the red zone with the Bills looking to take a 17-3 lead. Tuel fired a pass into the hands of Sean Smith, who plays for the Chiefs.

Smith then proceeded to race 101 yards the other way for a pick-six that knotted the score at 10.
