He had 18 sacks last year. He has 53.5 sacks during his career, which started in 2004. So as a pass rusher he hasn't been consistently elite and has not done near as well this season getting to the QB. He is poor at defending the run. I don't know about him being overrated because I don't recall many people ever saying he was that great. He basically had a couple of good seasons sacking the QB over 2010 and 2011, but for most of his career has been less than average at creating a pass rush. He is not worth the money he was being paid, but he could probably help some team at a lower price. I don't see any team putting a claim on him, but after he clears waivers a team or two may have some interest.
