Wait why not trade Bowen, Udoka, and 2nd rounder for Chris WIlcox?
OKC just waived Bowen right away, while they get a vet SG as great complement for Kevin Durant and Russel Westbrook and you guys get Wilcox an expiring contract and get rid of Bowens contract and yet you get him back for a much cheaper price then there the Spurs again still a massive contender for the Championship
... Because we'd be completely screwed at small forward, and wouldn't have a star perimeter defender to contain guys like Kobe?
That trade would
never happen, I wouldn't even trade Bowen for Wilcox straight up if salary allowed for it to happen. His perimeter defense is a very important part of our success, and San Antonio won't just dump him for some more help scoring in the paint. Adding our 2nd best small forward to the deal makes it even worse. That would never happen.
As for the rest of your post... What do you mean by "OKC just waived Bowen"? No they didn't, Bowen's not even on their team. And if you're suggesting that they'd just waive him, then that's ludicrous. If by some miracle they obtained one of the best perimeter defenders in the NBA, you can bet they'd hold on to him and put him next to Durant on the wings. Durant isn't a very good defender, so Bowen would help him out tremendously. No way they would waive Bowen if they acquired him via trade. And who are you referring to as the veteran shooting guard that they are getting? If you actually meant that Bowen would be waived, then you must be talking about Udoka, who is a small forward.
I have no idea what you're trying to say in that second part of the paragraph, since you started the first part off so confusingly. I think what you might be intending is that OKC would waive Bowen, much like they waived Barry in the trade that brought Kurt Thomas to San Antonio, and then Bowen would sign back with the Spurs. If that is what you're trying to say, then there is absolutely no way that would happen. OKC would keep Bowen, they wouldn't waive him.
OKC gets a lot of help from this deal, whereas San Antonio gets raped. Sure, Wilcox is young, and I guess an expiring contract is a good thing (not to me; I want players that are going to help out long-term, and could care less whether or not they're expiring in a year or two), but it's not worth giving away our two best perimeter defenders. The starting small forward would probably be Finley or Ginobili playing out of position; it'd just be a mess. Your idea is not very good at all, and doesn't help the Spurs whatsoever. If it was Jeff Green coming over in the deal, I'd consider it, but this is just absurd. I'll keep Bowen and Udoka and hope Duncan, Oberto, Thomas, and Mahinmi is enough, rather than get a tiny bit of improvement in the post, and a huge hole at small forward anyday.
