I doubt Houston would be interested without serious future assets-- George is only signed for two more years, and Houston's not competing in the next two years anyway.

Guaranteed Houston would want Shamet too, and there's just zero chance the Clippers trade him with the deal they have him on. The Clippers could offer, like, PG, Kabengele, and a couple of second rounders-- but if Houston's trying to build the future, that's just not a terribly attractive package.
