Steve Kerr spoke about how the NBA has moved away from traditional power forwards in which those players are almost exclusively either centers or wings.

"The other thing that hurts all the centers is there's no four-man anymore," Kerr said. "David West used to be a four, now he's a five. (Kevon) Looney -- ten years ago would have been a four. Now he's a five.

"So as a result, we end up with six centers on a roster ... now you're either a five or you're a three. The four position has almost been eliminated from the NBA.

"Unless you're Draymond Green and you just play whatever the hell position you want to call it."
