Obviously, a trade down for the right price is the way to go. The value chart is not indicative of what they can truly get for the pick, but they should at least get something decent in order to trade down. I do not trade down unless they get enough picks to make a difference. Too many holes to fill here and giving up an elite pick for the sake of moving down is not the right idea. If the worst case scenario is that they do not move down and are "stuck" with the #1 overall pick and have 5 of the top 100 picks, then so be it.
All that being said, I think if the offer is both Dallas #1's, Marion Barber, and a #3, I have to strongly consider the deal. I would try to see if they could get a 3rd team involved and add some extra draft choices instead of Barber.
I think you have to go defense in round 1 and I would prefer 2 big players in the front 7 picked fairly early. The depth at CB is pretty solid and I think you can add contributors in the 3rd and 4th round.
The most important thing this offseason is to add 8 to 10 legitimate long-term starters. Hopefully 2 to 3 YOUNG free agents and 4 to 5 draft picks. This is why they have to trade Jason Taylor for a couple of draft choices. If you add choices for him, it puts less pressure on you to trade down from #1 unless it is the deal you want.
Thats it for now. Look forward to a busy 82 days til the draft.....
