In terms of knowing the game and having an amazing feel for it on the court, Artest has few equals. Combine that with his great length and strength, and it's obvious why he has been a special defensive player for years.
Alexander needs to build a foundation somewhere on the court, and defense is a good place for him to start. He's also long, strong and athletic, so it's about learning the game from a defensive standpoint and then prioritizing improvement on that end of the floor.
Playing with confidence on defense like Artest does means staying locked in, tough-minded and ready even after getting scored on -- similar to a cornerback in football. If Alexander can accomplish this, he'll find a place in the Bucks' rotation.
