"That's against my Own dang HS too!": When Stephen Curry was shocked by Zion Williamson's high school dunk 

Four-time NBA champion Stephen Curry was once so impressed by a Zion Williamson dunk – which came against his former high school, Charlotte Christian – that he shouted out the young phenom on social media.

Williamson, a consensus five-star recruit in the Class of 2018, was known for his powerful dunks, and he went off for Spartanburg Day School in November 2016. In that game, Williamson, then a junior, posted an incredible number of dunks, including one that left the Golden State Warriors point guard amazed.

In a reel shared by Overtime on Instagram, Williamson connected on an alley-oop pass to slam home a powerful dunk.

"yooo! And that's against my Own dang HS too!"
