Basically, this thread is to suss out the possible options for a Jefferson trade and to see what types of offers might be available for him. The reason I put "might" in the title is because we can think we know with certainty which teams those are, but that's never completely public knowledge. For example, how many people thought the Miami Heat would've been interested enough in Ricky Davis and Mark Blount to send a first-round pick back to the Wolves?
So with that said, here's a list of every team for whom I think there's at least a 10% chance they're interested in Jefferson and could send back more than cap space:
Charlotte - They took on Stephen Jackson's deal last year. They're tied up with Jackson and Wallace for the next 3-4 years. They just made the playoffs for the first time and would like to keep in that race with the possibility of moving up.
Chicago - I think this is unlikely because they're trying to catch bigger fish, but he's obviously an option on some level.
Dallas - If only because they're trying to win now and don't have a player redundant to Jefferson.
Denver - Highly, highly unlikely, but not impossible if they think Jefferson makes them better than K-Mart and another team is interested in Martin as an expiring
Detroit - This also seems like a fallback option because they want Cousins, but the Wolves might be holding the cards related to whether they can get him and could best facilitate a Jefferson trade by not effectively removing the Pistons as a suitor
Golden State - Unlikely if only because Don Nelson rarely has post players, but if he quit and a new coach brought a new style, there are players and contracts that might facilitate a decent swap
Houston - I think they'd prefer to use their cap space on better and/or more efficient players, but it's not impossible
Indiana - Another highly unlikely destination unless they can move Troy Murphy's expiring
Miami - Unlikely, but maybe a fallback to fill the 3rd-best player role if they can't get 3 of the top guys
New Jersey - Highly unlikely but not impossible since they offered Devin Harris and the #11 for him before last year's draft
Orlando - Highly unlikely, but they'll be over the cap for years and might want to re-load by getting another post player who can do things Howard can't
San Antonio - Highly unlikely, only if they couldn't get anyone better and thought he might push them back up to title-contender status
Toronto - Would be an obvious lower-level replacement for Bosh if they don't go for a total rebuild
