I want to see Houston go younger and faster. Surround Harden with a bunch of guys who do all the stuff Harden won't, and nothing more.
Maybe find another Jeremy Lin / Goran Dragic type to provide some playmaking off the bench during the ten to fifteen minutes Harden isn't playing, and function as a shooting guard otherwise.
Keep Beverley and Capela. See what Dekker and McDaniels can do. Let other teams take a chance on Jones and Motiejunas. See what they can get for Ariza.
They aren't going to get another superstar to put next to Harden. They won't find somebody else to be the veteran leader that team needs.
So instead, just try to maximize what they can get from Harden by surrounding him with guys willing to hustle and play around him.
Basically, a bunch of younger Corey Brewer types. Only they need to go after guys with better discipline and character. You can't surround a guy like Harden with personalities like Morris, Smith, Howard, etc. You need guys who will be accountable to a coach and most of all to themselves, even if the star player won't be.
