I agree that no one's untouchable, but here are the players I'd least like to be touched, in ascending order: Yao Ming: Last time he played, he was arguably the best center in the NBA - you're not going to get that value back in a trade. So just hope for now, and he expires if all else fails. Kevin Martin: A dynamic, efficient wing scorer is very valuable when you have a great low-post presence. His value goes down with Yao's, though. Luis Scola: For the next three years, I expect him to be a strong, starting-caliber power forward - you can never have enough of those. Aaron Brooks + Kyle Lowry: If we can't keep this tandem, we'd better be getting an All-Star point to replace it - otherwise our production at the 1 would drop off significantly.
