He was talking about getting the ball in the paint and drawing fouls specifically. Walton mentioned wanting to play with balance, both inside and out. The discussion centered around the inside game of Barnes.
Yes, and playing in the paint doesn't mean necessarily posting up. Walton likes to talk about "breaking the paint." It could be dribble drive or post up.
I think you're both circling around the same point: Harrison Barnes is good at drawing fouls, whether it's in the post, the point, on the perimeter, etc. And we're lucky to have him.
