Offensively, he's the most talented center of all time. Can score from anywhere, create his own shot, can create open looks for others, court vision and passing amongst the best of all time. Basically put the ball in his hands and you have an elite offense regardless of who else is playing with him. Now defensively he's not that good, he's not bad or terrible, but he doesn't have the athletic ability, mainly speed, quickness and length to be elite on that side. He can have good defensive possessions on his IQ, instincts and read of the game, but he won't ever be great on defense imo.
Since GOAT conversations will always depend on championships, individual awards and stats besides his play, he has a way to go to reach there. He won't ever be GOAT, Jordan just has way too much going his way. But he has the talent to be a top10 player ever, even without the elite defense (Magic Johnson being a prime example that it's possible), and he has time to get it as he's "only" 28. But as I said, he will need multiple championships and more elite seasons to enter that conversation. Not impossible
