As the Buffalo Bills handed the Kansas City Chiefs their first loss of the season, wide receiver Amari Cooper took a subtle shot at his former team: the Cleveland Browns.

That changed when the Buffalo Bills defeated the Chiefs 30-21 in front of a capacity Highmark Stadium crowd of 71,112 in Western New York. The game was the most important contest for the weekend and was highly anticipated between two of the AFC’s best teams.

Amari Cooper has seen a lot in his decade as an NFL wide receiver.
