The last bunch of posts make it sound like it will be the Cavs choice of whether or not they will keep Love - if Love wants to come back, of course the Cavs will sign him, regardless of money.
I just don't think Love will want to come back; however, if Love wants to leave on a good note, he can still get the Cavs a first round pick and a humongous TPE. As discussed, this does not benefit Love since [new CBA rules state] he cannot get as much in a s&t as he would simply re-signing with the Cavs, but at least he would be able to go to the destination of his choosing while not being the guy who screwed over the Cavs (even though Wiggins is likely better than anybody they will get with their first).
