I don’t think anyone would take Ayton over Sabonis. Sabonis is a three-time All-Star, 1 time 3rd Team All NBA, a better rebounder, scorer and VASTLY superior passer and has no motor questions, while showing the ability to be very good in both conferences.
Ayton has never sniffed an All-Star or All NBA team, can’t create for himself or others, was an absolutely horrid defender this year and his defense js consistently overrated here, evidenced by never being recognized or coming close to any All-Defense team despite as you say a dearth of good centers. Dude is the definition of empty calories who has now quit on his own team twice in the playoffs.
