The 2020 NBA Slam Dunk contest is here and three of the four participants played college basketball — Orlando’s Aaron Gordon (Arizona), Miami’s Derrick Jones Jr. (UNLV) and Milwaukee’s Pat Connaughton (Notre Dame) — all but Los Angeles Lakers center Dwight Howard.

Before these players were competing on one of the biggest stages to display athleticism in professional basketball — the dunk contest — they were throwing down acrobatic dunks at the college level.

We found some of the best dunks from their college days to remind fans of where these dunkers started.

Aaron Gordon

College: Arizona

Years active: 2013-14

Sure, we’ve all seen alley-oops before but what about a reverse alley-oop in transition against UCLA?

Because Aaron Gordon’s done that.
