A lot of people? What lot of people? Couple comments maybe ... in hindsight it's the 2010 injury that taints it most. Xanders (in his genius) wrapped him up before he hit the market a year later. I recall articles predicting 3-4 teams would have gone nuts, he would've set a FA record. Even with that lost season, he has 63 sacks in six years, how many guys average 10?
That contract - like all contracts - is a product of the environment existing at the time. Look no further than Joe Flacco for proof of that.
