If Waddle nets a 1st and 3rd, Pickens, at a minimum gets you a 1st and 2nd.
If this was going down with, let's say, NE, I'd want their late 1st this year and next year's, while sending back a 3rd next year. I could see the Patriots wanting to adding a young WR with Maye.
Yes, you'd have to replace Pickens with a pick, but having #12, 20 and 31 really opens up your board and keeps you from reaching. If you get wiped out on defense in the top 11 picks, then a top WR should still be sitting there at 12. Then you can get Edge/CB at 20 and LB at 30 (which wouldn't be as much of a reach as at 20.
