There is a wild card here: Love controlling where he wants to go. He can simply say "I will not sign there." That makes all of this pure speculation. Ultimately I think Boston ranks 4th behind these three teams: Lakers, Warriors and Rockets.
Ainge has said he'd trade for Love without an extension.
I think those are different things. Ainge doesn't expect Love to sign an extension (although one would certainly be offered) because it doesn't make sense for Love to do so. Understanding this, Ainge isn't going to stand on ceremony about it. This is the same thing with Rondo, and why Rondo won't be traded simply because he hasn't signed an extension. Ainge feels that by being able to at least match any offer made to the players due to having their Bird rights, he'll be able to keep them in Boston, and so isn't concerned about an extension.
However, if Love's agent told Ainge that Love didn't see himself wanting to stay in Boston after this year, even if offered a max deal, I think that Ainge would back away from a trade.
Agreed.
Agreed X 2
Agreed X3.
It's best for Love
financially to go wherer he wants to end up playing AND then not sign the extension AND then re-sign for 5 years with that team. If he comes to Boston and leaves, it would cost him money. I expect he'll end up where he intends to eventually re-sign. Ainge will have a side agreement with Love and his agent before Ainge does a deal. Same with any other team Love goes to.
By and large I agree with the OP's assessment of the suitors, but I wouldn't give up 3 firsts, especially without protection. Fear Bulls the most, but they're cheap. Cavs could put top deal together, but I have trouble seeing Love agreeing to go to a team with management than the TWolves.
