Joel Embiid is averaging 11.36 FTA per 36 minutes for his career. The next highest is Shaq with 9.66 FTA per 36. He is shooting 16% more FTA per game than the second place. The difference between Embiid and the second place is the same as the difference between second and 22nd place.

The gap between him and the second place is enormous. What does Embiid do differently that others couldn't consistently replicate, even in today's era? Yes, per 36 is not the right tool to compare different players and across different eras, and he is still playing in his prime, so his free throw attempts are expected to drop like other greats. But even in Shaq's prime, he was averaging less; shaq averaged 10.4 during his Lakers days with Hack-a-Shaq where players were trying to foul him.
