When training camp kicks off for the Cincinnati Bengals next month, one of the most heated battles will take place along the defensive line. The Bengals have done a great job of acquiring talent along the line over the past few seasons. They started with the second-round in 2013 by selecting Margus Hunt, and then added Will Clarke in the third round of 2014. This offseason, Cincinnati added both Michael Johnson and Pat Sims in free agency, and then drafted Marcus Hardison in the fourth round.
