I'm old enough to remember watching Wilt and Russel go at it. Jerry West vs " the Big O", at Cincinnati Gardens. Lew Alcindor w/ the Bucks. Riles and Doc as guards and a young Dr J of the Virgina Squires slamming a red, white and blue ABA ball. I attended a ABA playoff game in Freedom Hall Louisville, KY in 1977; DEN vs KEN that feat. David Thompson who had a 46"in. vertical leap (he could rake a Otr off the top of the backboard) and finally, Dunking a basketball was a tech when I was in high school! It wasn't allowed.
