As an old schooler, I think I know what you are saying. But to me "post-up" is a term that has lost all meaning. Just because you pass the ball to a "big" who has his back to the basket it doesn't really mean it's a post-up. In old school terms, the big had to be somewhere near the paint. Anymore, bigs have no idea how to get good (usually meaning"early") position, so defenders push them out 18-20 feet from the bucket. (This is especially true of LMA.) it is hard for me to call that a "post-up." LMA doesn't usually want to get physical enough to establish true post position, as long as he gets the ball. Consequently you get fadeaways, which are not very efficient, instead of strong moves that are actually toward the basket.
