To me, this is where what we do with Diaw gets complicated. If we let Diaw expire, we'll have a decent amount of free cap space next year (assuming we don't make any mid-level type signings). Probably not that huge though, I'm guessing around 4 or 5 million. Using that cap space, we can help other teams, specifically ones over the cap, with their trades by absorbing extra salary when the salaries of the primary players don't match, usually gaining a pick or young prospect in the process. Obviously, we don't have to do the space to do this now, but we could have a little wiggle room in the future. Whether or not any potential trades would actually materialize in the next year or two remains to be seen, and of course, whether or not we can weasel our way into a deal isn't guaranteed either. So it's a gamble on whether you gain any assets, but you get definite salary relief, which is probably attractive to Jordan during our rebuild.
Obviously, if we can flip Diaw in a good deal this year, we have to do it. I haven't seen or heard any realistic deals that really intrigue me though. For example, I'm not sure the deals you listed are automatic pull the trigger type deals. It seems, give or take, Reggie Williams can do basically everything Morrow can do (they even have the same back story), but Reggie's on a much cheaper contract.
I just think we could accomplish gaining the same type of assets that you get in a trade like that (Morrow/Farmar type guys) through free agency with the new cap space we'd have from Diaw expriring and potentially for cheaper (not that Farmar or Morrow are on terrible deals or anything). I think the best type of deal the Bobcats might get would be sorta how we did with Nazr, getting back another expiring and young player (DJ White) to evaluate. Obviously, Nazr seems like a better trade piece that Diaw to me, so I don't know what teams would realistically be interested in him.
I gotta lot of free time today so maybe I'll look around and see if any of the teams that might have an interest in Diaw have young dudes that I think could be decent fits here.
