My Ohio basketball knowledge begins in 1976, I'll go with:
Gary Trent
DeVaughn Washington
Patrick Flomo
Brandon Hunter
Lewis Geter
Snoopy Graham
And two notable dunkers:
1. John Beauford - at 7'3" it wasn't too hard for him to dunk. I did once see him dunk so hard in practice that he broke the supports for the backboard stanchion and collapsed the entire backboard (no shattered glass). It looked like one of Shaq's dunks in the NBA.
2. Jamie Brock - he is listed for the ferocity and fear that his dunks instilled in the opponents. As in "Get out of the way, he's going to kill me" dunks.
I like your picks and your 2 throw in notables with one possible exception. I don't remember Snoopy being much of a dunker. He was very unique player but I think he was as likely to do a George Gervin finger roll as to throw it down.
That late 80's period saw several exceptional dunkers visit the Convo
- Dan Majerle became a 3 point threat in the NBA but got his nickname "Thunder" with his dunks and they had a guard at the same time at CMU called "Lightning"
-Ron Harper dunking had comparisons to Julius Erving when he was in college
-Chandler Thompson I think would be remembered due to him playing so big for his height and being on the BSU team which played UNLV the closest on their run to the national championship in 1990.
** I have not yet seen Kenny Battle mentioned, maybe because he was at NIU one year before transferring to Illinois if I remember correctly. He was a highlight reel but seemed to be more interested in entertaining than winning. I remember near the end of a game in the Convo he had a fastbreak when the game was out of reach. Instead of letting it go, Rich Stanfel wrapped him up to prevent him from dunking. I think Stanfel learned the technique from his dad who was a coach with the Chicago Bears.
