Alot of teams need QB's and not all of them will be able to get Andrew Luck. In fact only one will.
If you look around the league right now and say "who needs a legit starting QB" I come up with (in no particular order):
Redskins, Niners, Seahawks, Chiefs, Broncos, Browns & Dolphins...now the Dolphins very well could end up with the 1st pick and get Luck, what about the other 6 teams?
And no, I dont consider teams with Tim Tebow and Colt McCoy set at QB.
We could definitely find a trade partner if we put Romo on the block, and somebody would trade something of significant value to get him. Hell washed up Donovan McNabb fetched a couple of picks for the Eagles didnt he? The Bears gave up two firsts for Cutler, and the Bengals got at least a one and a two for Palmer. Romo has been alot better than any of those three.
