I put together this list of centers that I consider minor (a few questionable) to significant upgrades. A lot of them are considered untouchable, but you never know. I think we have a very small "chance" on a few (if any at all) and a decent chance on the rest. I guess it all depends on what Dallas would be willing to give up. I think it is obvious we have plenty of variety as trade bait.
I included the salaries and contracts to get a better grasp of what is out there. Let me know if I missed anyone.
