2015 NFL Player Rankings: Defensive Linemen

When it comes to the NFL's top defenders, the list starts with Houston Texans All-Pro defensive end J.J. Watt. Now a two-time NFL Defensive Player of the Year honoree, Watt's jaw-dropping athleticism and big-play ability was on full display last season, as he not only terrorized quarterbacks, he also helped his own put points on the board thanks to his three touchdown catches as a situational tight end. While Watt is clearly the cream of the crop right now, he's not the only defensive linemen that is getting paid handsomely for his efforts either. Ndamukong Suh, the No. 1 defensive tackle, inked a record-breaking six-year contract with the Miami Dolphins this offseason that could be worth more than $114 million and is guaranteed to play the former Lion nearly $60 million.
