I suppose this might be a good time to mention Don Smith? No vids to proove it but wasn't he a part of the reason the dunk got banned for a time? (Iba, Alcindor also).
This taken from a Visions magazine interview with Abdul-Aziz:
What’s something about your collegiate career that people may not know about you?
This was great for Iowa State. It’s a historical thing, and a lot of people don’t know it. The dunk shot was banned in collegiate basketball. I was involved in the banning of the dunk shot! Henry Iba, he was the Oklahoma State coach. This is what happened: I got a rebound; I threw it down to a Peruvian player named Raul Duarte. He went in to make the layup, and he missed the shot. I came down and goaltended the ball … and dunked it. Henry Iba gets up off the bench, says, “That’s goal-tending, ref! That’s goal-tending!” They gave Iba a technical. He said, “I want to make sure the dunk is banned.” He was on the NCAA rules committee, and the next year they banned it. It was banned for seven or eight years. Most historians don’t know this started at Iowa State.

Editor’s note: An article from The Sporting News confirms this account, saying, “One spectacular play by Don Smith might have motivated Coach Henry Iba of Oklahoma State into predicting that the basketball rules makers would outlaw the dunk shot and eventually raise the basket.”]
