Veteran defensive linemen Geno Atkins, Carlos Dunlap and Michael Johnson have seen plenty of faces come and go in the Bengals defensive line room.
Through all the turnover in the front four, the trio has a combined 18 seasons of starting experience together. 2009 was the turning point for the Bengals defense going from the cellar to the ceiling of the NFL; and Johnson’s arrival that year, followed by Dunlap and Atkins joining him in 2010, were huge factors in the defensive revival under former defensive coordinator Mike Zimmer.
