As a fan living in Oklahoma, I'm all for this. Right now I consider this a short term win that can turn into a long term W... only if Presti can sucessfully rebuild the team. I personally still hold him in high regard and most fans don't blame him for the direction of the franchise post Harden/KD/Westbrook era(It was the owner that didn't want to pay Harden that set the events in motion). However, he will be on the clock on while undergoing this rebuilding project. Right now, he's doing everything correctly.
Trading Westbrook was smart and necessary because Russy is what he is, and outside of a soul-searching miracle, Westbrook isn't going to change his personality or his game. I won't say you can't win with a player like him, but it's very difficult. Plus, Donovan cannot control a player like Westbrook, so the best thing you can do is to ship him off! Even if, somehow, the Rockets win a championship with Harden and Westbrook, this trade was necessary.(Y'all gonna talk shyt forever tho).
Now, as to why Chris Paul? The answer is quite simple. He has one year less than Westbrook on his contract which won't matter if you're gonna be losing/not making the playoffs any time soon. I personally believe that Chris Paul has some value, but he will have to prove it next season. I think CP3 would be a good mentor to Schroeder or any of the incoming PG that OKC will draft in the near future, but I seriously doubt that he would want to do that for the next 2 seasons, then retire.... he wants a ring, so he's gonna try to play his way out of OKC to a contender before the trade deadline next season. If he cannot do that, then he truly is "washed" and needs to retire.... or just retire now and be done with it.
This trade for Houston, "could" work out, but I'm leaning towards it being a long term L... because of the reasons I stated about Westbrook's ego and game, in addition to the fact that D'antoni cannot make this union work neither. Harden and Westbrook aren't the young guns from OKC trying to make a name for themselves... Harden should have been more careful for what he asked for....
Hopefully, Sam Presti can rebuild OKC fairly quickly and not have OKC in perpetual rebuild mode like the Knicks.
