Rational people can not be a fan or a school/team but still respect great coaching of a dynastic program. I'm not a NFL fan at all but I respect what Bill Belechick is doing. Spurrier was a jack-butt but his coaching impressed me. I think Urban is a horrible human and excuses bad (even criminal)behavior from players but he's a great coach. Pat Summit at TN was one of the best coaches of all times. I'm not a fan of TN girls basketball. Great leaders come in all shapes and sizes. Many of them are not necessarily great people, but great leaders.
I've never met Saban but hear he's a likable guy in person.
