25. Russell Westbrook
Russell Westbrook first showed his teeth on defense back in college at USC, when he was named the Pac-10 Defensive Player of the Year in 2008. Westbrook has carried that defensive intensity into the NBA as one of the best on-ball defenders in the league.
Westbrook has averaged 1.7 steals per game in his career and has proven to be an incredible rebounder at the point guard position.
