This one is so beautiful and so ugly. It turned from a chippy AFC North battle into a full-fledged rivalry when Bengals head coach Marvin Lewis came to Cincinnati in 2003. In 2005, the resurgent Bengals met the Steelers in the AFC Wild Card game when Steelers lineman (and former Bengal) Kimo von Oelhoffen tackled Bengals QB Carson Palmer low -- and Palmer got twisted and tore his ACL. The hit came on Palmer’s first and only attempt -- a 66-yard bomb to Chris Henry. The game remains a bitter memory for Bengals fans as the Steelers went on to win the Super Bowl.The ensuing 10 years saw heated battles, a lot of Steeler wins, finally a Bengals season sweep in the 2009 season and come 2015, things started to get uglier, culminating in the AFC Wild Card penalty flag fiesta that saw some truly bizarre events: a personal foul on Steelers offensive line coach Mike Munchak for grabbing safety Reggie Nelson’s hair on the sideline, and later a personal foul on Bengals DB Adam Jones for making contact with an official when Steelers assistant coach Joey Porter entered the field of play. It was mayhem.“I actually saw [the rivalry] really turn into what it's become last year” said former Bengals wideout Marvin Jones. "It was always heat of the game, but it never got too frisky and stuff like that. It was just always a good, ground-and-pound AFC North game. But after last year obviously it spiked up and I'm not going to say I didn't like it. ... It just made me feel like, 'Man, this is football. This is gritty and this is grimy.'"It’s gritty and grimy and sometimes rivalries bring out the worst out in players but more often it brings out the best. The first Bengals-Steelers matchup of this season was relatively peaceful as far as those games go.
