I'd count all those guys you mentioned
Honestly, the list is going to be pretty long. Here are all the potential candidates just for teams in the KenPom's final top 50 from 2021. The school they played for in college is in parenthesis. Some may not think of Huggins and Boeheim because that was before the TV days. And maybe not Tony Bennett, because he played for a mid-major. But, he was a dynamite scorer who also played in the NBA for a couple of seasons.
