While I agree with you, I think HOU will be lucky to get much more than cap relief for Asik. Yes, Perkins IS horrible...but would be an acceptable back-up for 10mpg. But if you're the Rockets, who are currently dealing with a supposed championship roster with chemistry issues, centering around a guy who's going to cost them $15M next year, who's a duplicate of your centerpiece, you're going to move that guy no matter what. Both OKC and MIA can sweeten the deal with picks/etc. I chose those two teams to illustrate how easily two current contenders could snap up a guy who would GREATLY help them in their quest to win a championship. I think it adds weight to the argument of US trading for him. If OKC or MIA can get the guy that makes it MUCH harder for us to be contenders. If we get him it MAY mess up chemistry, but it should improve our defense and it could deprive our main competition of a player they badly need.
As I said in my OP, I'm not sure that we should make the trade. But it certainly merits consideration.
