I don’t get this. Throughout time we’ve seen plenty of the best big men provide both. Duncan, robinson, Ewing, embiid, shaq, mourning, olajawon, kareem, Moses. Most don’t excel at both ends due to skill or physical limitation (dikembe’s lack of offensive skill, jokic’s limited athleticism) but it’s not because it’s too much to do both. Ayton was the #1 pick in a loaded draft. He is extremely athletic and moves really well. He is not limited by his athleticism on the defensive end and he has considerable skill on the offensive end. I would expect him to excel at both ends of the court.
