LeSean McCoy injured his hamstring five days before the Bills squared off with the Miami Dolphins. There were some initial reports floating around that he wouldn’t be able to suit up, but he ended up being a game-time decision and the team thought he was healthy enough to play.
If you watched the game, it was obvious that he was not. He lacked the burst and cutback ability that has led to his success all season and throughout his career. He was pulled from the game after having issues with the hamstring and in hindsight, it seems like it was a bad idea to have played him in the first place.
