Gosh darn Houston could be one of the worst trade partners we can ever have.
Who or what would they give up? Asik, Lin, 1st rounder/s? Harden is young, Parsons is young, Howard is relatively young, so those first rounders won't even sniff top 20 for the next 5 years if they add Rondo to that mix. And I doubt Morey will be willing to give up any of those three.
And I like Asik and Lin, but they are not on Rondo's level (that's combined). I see no one else on that roster that's worth while.
Danny isn't going to do this, he'd be crazy if he will.
