I'd be shocked if Hump is traded, just because his expiring contract is more important than whatever schlub would be sent our way with a matching salary.
I could see a deal in the framework of Hump/for Okafor and one of the later first round picks for Phoenix. We don't need Hump and he could help them. They can't realistically draft 4 players in the first round. I doubt they have that many open roster spots and you probably wouldn't want to guarantee that much money to four different guys for four years each unless you were rebuilding.
