Harden wanted this reunion, Westbrook wanted to come here and Tilman wanted fireworks, so Morey had no option but to do it. The power of players is getting a bit out of hand here, but it's a risk that might actually run Morey away from the Rockets organisation. Harden got his wish and both those guys wanting to reunite makes this trade better than it appears to be at first, though a former MVP in his prime over an aging star is a good trade on paper.
