Yep, its feels like the Shaun Ellis vs Abraham conversation again. I preferred Abraham, who had double digit sacks for the next 25 years or so after he left...while Ellis was a nice steady eddy performer.
Richardson will go into the HOF and Wilkerson will be a very good player for his career. That's probably how it plays out. I would love to keep Richardson over Wilk, but if you can have Wilk for 40 and Richardson for 60...it will be easy to see why the jets kept one over the other...and those are the two numbers I expect them to get.
And Wilk is better than Quinn and Jordan.
With that potential, think of the haul in a trade Richardson could get. You could get a mint for him, including firsts that might allow you to trade up and pursue one of the top QBs next year, if you still had a hole there.
