This entire thread seems based on a misunderstanding of analytics as "3P > 2P so analytics people only want 3s", when actually that those analytics say that 40% 3P is way better than 50% 2P. Prime Shaq was shooting almost 60% (over 75% inside 3ft), so that alone puts him almost as efficient as 40% 3P shooting, and when you add in the free throws he goes well above it. Reduce his volume a bit to increase his efficiency and you'd end up with an even more efficient scorer, and one that has so much gravity that it helps open up your 3P shooters even more.
If you ask actual analytics people, the best shot isn't an open 3, it's a dunk, then an open layup, then a three. That's why the Morey/Harden Rockets basically scored exclusively in the paint or from behind the arc. Even if you don't like Joe's pholophy or coaching style, saying he would ignore more efficient inside scoring because of an obsession with 3P shots is dumb. Joe disagrees with you about the best way to play basketball, but that doesn't make him an idiot,but he would have to be to ignore Shaq's efficiency and game-breaking ability.
