The thing I liked about spurrier is that, while he was a stubborn prick who could burn opponents on any given day, he had a sense of humor about himself. He could laugh at himself, even though he hated losing. I think that if he lacked that, he'd be terrible.
But love for him outside of the fanbases he coached is relatively recent. The press hated him, other coaches hated him, he just didn't give a shit.
Are florida fans upset at him for leaving when he did? Not at all. Will South Carolina's fans be all that mad? No, they won't. At least not for long. He gave that program a lot, even if they only won the division once. He put that team in the conversation for years.
I also don't get the argument that he's a coach that was too obstinate to hang it up. He just did the opposite of that, he's getting out because he realizes it's not working anymore. It's way better than Bowden who lounged around in a figurehead fashion while Jimbo was making all the calls for some time. Then when they finally ditched Bowden, it was a bit of a shitstorm as he went out with a bit of a grudge. That, to me, is worse.
