You're correct as far as I know...those are the only remaining teams with salary cap space above the MLE.
Not a good fit
Toronto - Bosh+Odom is a bad mix because both are a little too skinny for their position.
OKC Thundah - Already have a skinny frontcourt with Jeff Green & Kevin Durant. Doesn't make sense for them to add yet another skinny forward to their team.
OK Fit
Portland - Already has LaMarcus Aldridge playing heavy minutes. Along with redundancy in Oden/Pryzbilla...would they want to pay $10 million plus for a backup?
Good Fit
Memphis could put up the money and could really use Lamar to go with the tank-like Marc Gasol, Rudy Gay and OJ Mayo.
