Zion Williamson is one of the most impressive dunkers in the NBA. Despite being bulky in appearance, he has ridiculous athleticism as can be seen in this clip.

The 21-year-old Pelicans forward casually made a windmill dunk while wearing regular clothes in front of a group of kids. One of them appeared shocked.

One thing is to see Williamson dunk on TV and another when it is done right in front of your eyes.
