@Lulufulu I agree 100%. But I don't think Self is saying to necessarily have the post guys shoot more from outside. I think what Self is talking about is still getting shots close to the rim, but getting the ball to the guys differently. Our standard deal is the post entry pass to the stagnant big guy on the block. He's referring to the bigs receiving the ball in different ways, I believe.
For example, perhaps, more direct flashing across the lane (coming from the other side toward the ball), elbow to box slide (post at the elbow and slide down), some low to low exchange (movement between two bigs box to box -- or even elbow to box) or some screening action. I think that's what he means by "work(ing) back in."
Again, that seems real positive to me. But as you say, "talk is talk."
