Okay, so nobody thinks this can happen because of the CBA but I don't see why not.
Let's say the following occurs....
#1 Pick: Panthers select Blaine Gabbert
#2 Pick: Broncos select Dareus
#3 Pick: Bills select Newton
#4 Pick: Bengals select A.J. Green
#5 Pick: Arizona is on the clock.... no good QB's left, oh no!
Howie calls Arizona's GM and says, we'll trade you Eagle's 2012 1st, 2nd, and 3rd round picks for Arizona's 2011 1st and 4th round picks. (This should be 100% fair, if it's not then use your draft value board and adjust it accordingly)
#5 Pick: Eagles select... Patrick Peterson
etc. etc. etc. etc. Draft ends
CBA is resolved in August 2011.
Eagles trade Kolb to Arizona for Arizona's previously aquired Eagles 1st, 2nd, and 3rd round 2012 picks. Net result: Eagles get Arizona's 1st and 4th round picks in 2011 and get to use those picks this year. Arizona get's Kolb this year and no 2012 draft picks were lost/gained.
Okay, so the big question is OH NO, what happens if a team backs out and changes their mind.
Bad Scenario #1: Eagles decide to keep Kolb because Vick accidentally ran over his neighbor's dog and went back to jail. Arizona gets to keep Eagle's 2012 1st, 2nd, and 3rd round picks which they could easily trade for another QB or just prosper next year. Eagles get to keep Kolb and the 2011 1st/4th from Arizona (peterson/etc)
Bad Scenario #2: Locker drops to 4th round due to inaccuracy concerns and Arizona gambles on him and no longer wants Kolb. Eagles trade Kolb to Bengals, Dolphins, or any of the other 15 teams that needed QB's for 2012 1st and 2nd rounders. And we still got to keep Peterson and Arizona's 4th rounder in 2011 and we get back our 2012 picks from another team.
Seems like a pretty safe deal to me. So the whole point of the post is that I think it's stupid to trade Kolb after the draft for 2012 picks. Vick is set to go for a Superbowl run now.. he has only a few good years left as a mobile QB. so any help this year is substantially more valuable than picks next year.
