There are very few players I can't think of that can get to the basket and finish as effectively as Zion. What is he doing technique-wise that makes it look so easy? The moves leading up to the finish seem different than other players approach to driving, but I can't put my finger on it. Some of his finishes are spectacular, especially working through double teams, but most are very basic drives that just involve a single fake to get the defender moving one way, then slash to the hole.
The part I think is unique is that he pivots and jumps at the basket in both the vertically and horizontally direction, doing it very far and fast. I think he using every bit of extension coupled with his vertical. And adding to that, he is always looking for the rebound after his shot or a block, plus he has great touch and offensive IQ positioning his body making it all very unguardable.
A lot of people are gonna say because he's big and athletic and while that has SOME to do with it it's not completely the reason why he's so good at it. The reason why is because he has mastered the art of driving. You don't need to be super fast or strong to be able to drive and get to the basket, it's all about a quick first step, momentum shifting and knowing the correct angles to drive effectively. Some players are elite at this and it's why they get to the basket at will. For example, Luka isn't particularly fast, but he's INCREDIBLY elite at getting to the basket at will because he's perfected the art of changing his momentum and guiding his defender with his body by abusing angles. Another one is LeBron who almost always gets past his defender whenever he drives to the basket. It's not about strength, it's about technique. Zion is elite at this on top of his already incredible athletic ability which helps him as well.
This is why harden was so elite too. You dont see unless youre in person but i was blown away by his first step live.
