Warriors, Nuggets, Gizards, Suns, & Mavs - None of those play any D.
Whenever people say that the Mavericks don't play defense I wince. I'm not trying to base things entirely off statistics, but Mavericks allow the 6thfewest points per game, and you're not going to be a bad defensive team and be in the top ten in fewest PPG allowed. They're behind the Spurs, Boston,the Rockets, the Pistons, and New Orleans.
I always say, if you made that statement a few years ago, that's fine, but Avery Johnson hammers defense into the brain of his players.
