I never heard that about Chuck. What happened?
Two things that I've heard.
1. He was pissed that his jersey was retired so long after Charles Barkley's even though he probably had the better college career and stayed around all 4 years. (I've heard, but can't confirm, that he wouldn't even come to Auburn for the ceremony when we did decide to retire it).
2. He wasn't consulted when Auburn hired Jeff Lebo even though Barkley was (and recommended Mike Davis).
Apparently he still carries the bitterness around with him and does not speak highly of Auburn.
