That's the nonsense Pop spews but it's simply not true. Defense isn't something played by just super athletic people. In fact sometimes the more athletic players are the worst defenders. Defense is played with smarts, desire, and commitment. Look at the '11 Mavs. They played championship defense and they're probably equivalent to us athletically. Look at the older Celtics the past few years. Let's stop with this myth you need all A+ athletes to play better defense. You need a coach and players that are committed to defense.
