But many other players do still have visceral memories of the first time they [dunked a basketball]. The Athletic collected these anecdotes throughout the season, and we’re releasing them now because, hey, why not? Michael Porter Jr.: I think I was in sixth grade in the summer going into seventh grade. It was outside. We had this hoop outside our house and I had spent all day trying to dunk. I got my first one that summer. I knew it was coming. I felt good that day. I forget what happened, but I just went outside because I had all this adrenaline. So I just tried to dunk and I got it. I was probably 6-foot or 6-1. In eighth grade, I was 6-3, so I was probably around 6-foot.
