Michael Jerome Cooper checked in at 6-foot-5 and just 170 pounds, but he used arms that seemed as long as a line of bumper-to-bumper traffic during rush hour to completely dominate on the defensive end. "Coop" ranks in the top 10 in franchise history in both total blocks and total steals and is the only Lakers player ever to be named Defensive Player of the Year. (Mike Powell/Getty Images)
