Martin has a GREAT reputation for his integrity. He's been criticized for other stuff, but he's generally viewed as an honorable guy. The quote from this website is similar to what I've seen from other fans of teams he's coached:
"Cuonzo was a good coach and a great man. I'll look back fondly on the way he developed his players on the court, in the classroom, and in the community."
