Really more and more, he is reminiscent of Joe Barry Carroll, for anyone that remembers his career.
Carroll also had a ton of physical ability, but just clearly didn't enjoy playing pro basketball beyond making a lucrative living at it. He had some good statistical years but never came close to maximizing his output nor having the impact he could/should have. After a while, even the money aspect wasn't enough motivation for him and it was apparent he mostly hated playing in the NBA after the first half dozen years he was in the league.
And by all accounts, Carroll wasn't a bad guy or disruptive influence. He clearly just didn't care for what ended up being his major career, probably not so different than many other people but just in a higher profile way. After basketball, he went on to other successful ventures.
It's pretty easy to see Ayton's career going in exactly the same direction, and probably for essentially the same reason. At the end of the day, pro basketball is just a way to make money for him and he really isn't motivated by anything more than that.
