If you can imagine a guy who went through school at Alabama, played at Alabama, and then Coached at Alabama... leaving to go to Auburn, you might understand that Auburn fans are slowing realizing that the sky is the limit with CNS.
.... someone like, say, Bill Oliver???
I was attending the University when Brother left for Auburn. I remember the feeling of betrayal and hatred. Others on here may have a better take on the situation than I do, but my pain has dulled with the passing years, and I now consider Brother Oliver to be a Bama man. I think he loves Bama and Coach Bryant, and I doubt that ever changed much.
I would bet that Willis still loves Auburn, even though they hate his guts at the moment.
Oh, and even when Brother left us for Auburn, I never felt like "the sky was the limit" for Terry Bowden. I think his limit was somewhat lower - around 4'-10".
