A.J. Klein
Bills Mafia just can't get rid of this guy. Every time we think he's played his last game with the Bills, Coach McDermott brings him back. With the injury to Tyrel Dodson, Klein was called up from the practice squad, and thankfully so, Terrel Bernard was later injured, and he too was out of the lineup. Klein doesn't jump off the page athletically and is a bit of a liability in coverage, but the staff trusts him, and he repaid that trust with an excellent performance.
Klein had a game-high 11 total tackles, including seven solo. Against a Steelers team that prides itself on its run game and toughness, Klein brought it and showed the Bills can play that game just fine. According to PPF, he had the highest tackle grade on the team, earning an impressive 83.0. He was the perfect man for the job against a Steelers team that plays to Klein's strengths.
