Hoops hype has it right, but its not applicable in this context. Their cap hits for teams that acquire the players via trade is the same for Houston; spread out. I'm not sure how that translates into actual dollars paid out to the players, but capsize that's how it breaks down.
If we were able to trade Piercd for Lin, Asik, and a first, that'd be highway robbery for us.
Here is a trade you have to wonder if it would work:
Pierce+Shav+T-Will+White (all unguaranteed, roughly 18.3 million), Bradley
For
Asik, Lin, Royce White, Terrance Jones, 2013 first
