Suns want him gone for a reason. Never underestimate the importance of guys being on the same page and feeling united.
I get what you're saying here, but this is how you attain an upgrade at talent by passing off players with lesser value. When guys have red flags, it drops they're value. Rondo, for example. Remember when we traded for a disgruntled C-Webb? I think he would be a really nice piece to add, he's still young and has some upside, but of course, you wouldn't want to give up too much.
Maybe something around Mclemore and Butler? How do you send over a trade exception? Salaries don't match up, but they would get someone young and with upside, as well as Caron who may be able to act as a locker room stabilizer. I'd love a young athletic big like that, but not without proper research, of course. I don't recall ever hearing any negative publicity on the twins when they were at Kansas.
