Tennessee won't give up that much to move up - why should they? They are in the position of having one of three stud players (assuming Bush also declares) drop to them. They can't mess it up. They either take their qb of the future or their rb of the future (brown would be a good complement to Bush).
So, I doubt they deal . . . . . . UNLESS . . . . . . one of the QBs distances himself from the other during the next couple of months, creating enough incentive for Tenn to want to jump in front of NO.
As a side note, I have to laugh about how everyone is willing to deal down NOW. When we drafted Carr (and AJ and Dunta) I wanted to do what everyone is talking about. Trade down, turn one pick into a lot of picks over a few years. I would have been wrong to do it with the AJ and Dunta picks (any doubt that Tenn would give its pick for either, I don't think so). The Carr pick is still unknown because he hasn't had a chance.
My original suggestion was similar: Trade down several spots from #1 overall and get multiple picks including picks over the next three years; repeat until you are into the 3rd round. If you could get close to fair value (off the point chart and figuring each pick moves up a round in value per year) then you could turn one pick into five number one picks next year (thats is even allowing a top value of 580 for a second this year). Six, if you deal our 2nd rounder.
PLUS, if you deal for picks 3 or 4 years away, you really clean up. Think about Dallas; Parcells will not be around forever so they need players now (a few teams will have that attitude due to aging superstars, etc.). So, we give up our 2nd for a 3rd next year and a 1st the year after (technically more according to the point chart but 1st round picks are harder to get).
If done right, by trading our #1 this year, we could have 3-5 picks in each round of the 2007-2010 drafts (lots of scenarios with where the picks fall but this makes my point). Two side effects of doing this; i. we keep sucking for 2 years so our picks would stay high, ii. we can fix our cap problems (and would want to deal our older high paid vets like Walker and RSmith).
If I were GM, I would have done this year 1. Now, I don't know. We have some stud players (and Andre would refuse to resing if we weren't trying) so we could slowly build. But, by not dealing for future picks, we either need to be real lucky with who we select or it will take us years to become a decent team.
BUT - if we blow up everything and take VY, then I would do this with the rest of our picks and trade our aging vets for offensive linemen.
