They just had a piece on ESPN about this in the NBA, post touches are down overall, they are a dying part of the game. It gets covered up by the idea that big players are more skilled today but in reality, they are less skilled. Post moves take more practice and coaching that shooting and dribbling. It gets talked about over and over again but club ball, aau etc...aren't typically coached by great coaches. People who don't know the fundamentals of post play are the ones teaching young kids the game.
