It's not even close.
Shaq could dominate on both ends of the floor, defensively and offensively; I don't know why people acting like Shaq in his prime wasn't elite defensively; the Lakers don't 3peat without his defense, as well as his offense, of course, but to act like Shaq was mid on defense is just revisionist tales.
Jokic is all offensive with the occasional defensive play, but don't count on him to defend at a high level consecutively, and the only way he wins is by outscoring Shaq, which wouldn't be easy, especially in the paint.
