Aaron Kampman isn't getting nearly as much interest as Julius Peppers.
He's recovering from a knee injury, and he only managed 3.5 sacks in 2009.
But that's largely because he played outside linebacker in Green Bay's new 3-4.
Before that, he was one of the game's most dominant -- and productive -- defensive ends. He had 15.5 in 2006, 12.0 in 2007 and 9.5 in 2008.
Not too shabby.
Right now, it sounds like the Bears, Detroit Lions, Philadelphia Eagles and Seattle Seahawks may be interested in him.
A league source told me that Kampman's left knee is ahead of schedule.
Kampman is a two-time Pro Bowl selection.
