Talk to anyone who knows George McGinnis and they'll tell you the same thing: he's as nice a guy as you're ever going to meet. He's soft-spoken and preternaturally polite, true to his nature and the habits his parents, Burnie and Willie, instilled.
That's not all that unusual, really. Most great athletes tend to be accommodating in their later years, after the cheering stops and the spotlight dims. I can tell you from personal experience, however, that McGinnis was the same way when he was on top of the basketball world, although I had to stalk him to find out.
