Gregg Marshall was certainly a prick to a lot of people, primarily those who annoyed him. If he respected you, though, different story.
Just before the whole College of Charleston thing, I was doing a story on him and he calls me back and gives me his cell. "Don't worry about Sports information. They won't help you when you need to get ahold of me." So when he bolted to CofC and then turned around and went back to Winthrop, my job was significantly easier.
Funny story: One year during a golf outing, I'm parking my cart to approach an early tee box when I'm slammed into from behind by another cart. I turn around, and it's Marshall and another coach in the league, just laughing hysterically. I pull out a handful of tees out of my pocket and wing them at him. Overall, maybe the best foursome golf outing I've probably ever had.
