It wasn't over Manning, it was Greg Dreiling, a 7 footer. Big 8 tourney in Kemper. ISU started slow. Refs were bad. Grayer got ****** and took it to the rack over Dreiling. I was sitting right behind the basket and will never forget it. Don't think I could rank them, but this dunk and Fizer over Mihm are easily top 5.
For those of us that are older, Terrance Allen used to absolutely sky as well. Back in 83/84, we ran an inbounds play under our own hoop, TA came straight down the lane and rocked the house. AWESOME!
Cato's spin move versus Cincy was awesome because he was not great in space and shocked everyone. By the way - it made One Shining Moment that year. Available on iTunes.
