That Portland would be willing to trade 25 if someone would help them clear salary. Harkless and Evan Turner are the names. They're not trying to get under the cap, they are just trying to make sure they don't go over the LT again so they can reset.
Boston would trade 2 of their picks for a good low priced vet. They are all about clearing any room they have for signing vets to make one more run if Horford and Irving opt in which would mean their hands are tied because of the LT. If either opts in but the other doesn't, they still won't have enough room to sign anyone of value. Their 3 picks are holding $8.5 million of critical room. There are too many variables. The rumor here is the Kyrie and Horford are playing their future close to the vest as their agents put out feelers.
The Kings are willing but not desperate to move Harrison Barnes if he opts in. They would entertain resigning Cousins again but don't think he'd sign. They would also like to acquire a 1st round pick. If Barnes opts out, they're not sure how they could sign enough salary to be even close to the cap. If Barnes opted out and they renounced all their free agents they'd have 80 million in cap space and no one good willing to take their money.
The Knicks are a mess and they know it. The rumor isn't that the Knicks rejected the Hawks interest in 3 because they didn't like it, the rumor is they didn't know how it helped them attract talent outside of the draft. If they waive their non-guarantees and renounce their free agents, they have $67 million to play with. The rumor here is they want to move #3 for a player that moves the needle for possible free agents or use future assets to trade for someone to move that needle. The Hawks assets were outside the range for the players they're interested in (all of which fall 4-7). They are all done developing talent. They want out of the lottery treadmill. They want players who move the needle now and are willing to move their picks if that's what you have.
Miami will again look at trading Whiteside once he opts in and will dangle #13 as long as they get something of value back in return that helps them round out a roster. They have asked Whiteside to make his decision predraft so they can explore options and include him in the process. Whiteside hasn't opted in yet as he's asking for considerations in where he can go (all private conversations)"
"As for Whiteside, he came to AmericanAirlines Arena to work out in recent days. Miami is expected to again explore trading him once he opts in. 1 week ago – via Miami Herald"
Most of this comes from people I know in different cities listening to local sports talk or similar. Some from tweets and such cobbled together.
Charlotte and Cleveland want their picks and have ideas on who they want at this point.
Lastly, there is only minor interest in the Hawks bevy of 2nd round picks and such. They have too many assets and teams know their supply issues and are trying to take advantage of it.
