If you haven't heard of Zion Williamson, chances are you probably aren't very active on social media.

When it comes to dunking, the 17-year-old is literally a human highlight reel.

Even though it's the summer, the highlights aren't stopping and Williamson proved that Thursday night with this incredible 360 windmill dunk.

 

 

OK, Zion Williamson 😳

Insanity, pure insanity.

The dunk Williamson threw down was ahead of a game at the HoopSeen Best of the South. 

He and his team lost a thriller to Each 1 Teach 1 70-67, but Williamson was brilliant in the loss.

Williamson followed that effort up with a 32-point game in a loss on Friday.
