Ranking the NFL's best D-lines

Ndamukong Suh has earned a reputation as one of the most ruthless defensive linemen in the NFL. Kellen Michah/Icon SMI

With Detroit off to a 2-0 start, we've been hearing more and more about the strength of its defensive line, a group that still doesn't have Nick Fairley in the rotation. But have they progressed to the point where they're among the top units in the league?

I evaluated all 32 teams to come up with what I consider the five best defensive lines, based on performance, depth and the likelihood they can maintain the form.

1. Detroit Lions

Kyle Vanden Bosch is the leader of this defensive line, and his work ethic and hustle are infectious. And Vanden Bosch has also been extremely productive thus far this season. But the man that makes it all go for Detroit is, of course, Ndamukong Suh.
