Irvin hasn't set the world on fire this year, but he's been solid overall, and knows our scheme.
He's an important player against big running QBs like Newton, and formerly, Kaep.
In particular, Irvin's speed kept Kaep from running on "The Tip" and other plays and induced that throw from Kaep.
He's kind of a hothead/meathead/legend in his own mind, without quite all the football savvy just yet.
His speed and athleticism are practically off the charts. (Thankfully, he's no Aaron Curry)
I'd like to see us keep him, if at all possible. Recall that he didn't really even play football until college. I believe he still has some good upside. Another year or two of maturity wouldn't hurt either. He's worth keeping if we possibly can.
