I've always been able to jump. When we were little, playing tag and stuff, I could always get away from guys by leaping over fences. One of the reasons I like to play defense so much is that it can help you get dunks. If you get that steal, you can fly downcourt and throw it down. I love that.
Defense is heart, for real.
It's just knowing you can stop the guy and wanting to do it. If the guy knows you're dedicated to defense, it can make him scared. Everybody likes to try the fancy stuff now. Like the Allen Iverson crossover. I watch and watch and try to sense when the guy's going to do it.
