Come on now! I have been observing former-Celtic Don Nelson since his days in Boston, and I am not convinced that was him at the Basketball Hall of Fame Ceremony. You be the judge.
Don was young in the above photo, and he has that boyish there-is-not-an-ounce-of-meanness-in-me look. Referees must have had a tough time calling fouls on him.
Now we see Don with the Golden State Warriors in his second stint there. He had added some weight and some age, but we can tell it is still the Don Nelson we knew.
