Poll Friday: NFL's best defensive line

The AFC East spent time with the Buffalo Bills in training camp this week. It was impressive watching Bills defensive linemen Mario Williams, Kyle Williams, Marcell Dareus and Mark Anderson work as a starting unit.

That prompted this "Poll Friday" question: Which team has the best defensive line in the NFL? The Bills have to be in the mix after spending more than $100 million on defensive ends in free agency.

Buffalo is in the mix with teams like the defending Super Bowl champion New York Giants, the always stout Baltimore Ravens and Chicago Bears. If we missed a team with a better defensive line, click other.
