The Pistons are aggressively pursuing Cousins as an offensive-minded replacement for Ben Wallace, who dominated the paint during their extended run of championship contention. The Pistons have been offering a swap of picks along with shooting guard Richard Hamilton in hopes of moving up to take Cousins. But the salary cap will be an issue as Hamilton has three years remaining on his contract at $12.5 million annually, which would eat into the cap space of the Nets, (who own the No. 3 pick) the Timberwolves (No. 4) and the Kings (No. 5).
