You think Jefferson is one of the better post players. Am assuming that's primarily off of just watching him play, seeing him in the post. I dunno what sort of "convincing" you're looking for, and I really don't care to, I dunno, comb through game film to show post moves or whatever it might be. It's a fairly simple stat to look at. I can say so and so is one of the better 3 point shooters. If you said well a guy with a higher percentage is better, and show me what he puts in on a per possession basis as being better than player X I named, what else am I needing to see? Clips of his stroke? On a simple per possession basis, if you post up Al Jefferson 100 times, and post up Aldridge 100 times, you're going to end up with more points out of Aldridge. Maybe scoring more out of the post doesn't specifically make him a better post player.
