Bear Bryant

Paul (Bear) Bryant won sixty games at Kentucky in eight seasons (1946-1953) before he left for Texas A&M.  He is still the winningest Wildcat coach after 60+ years.  The average wins per year since Bryant left is just over 4, so a coach would have to last 10-12 years if the won 5-6 games per year.  I don't see that happening at Kentucky - where a coach may last 6 to 8 years.

By the way, Bryant's record at Alabama was 232-46-9.  Nick Saban has now won 116 games as head coach of the Crimson Tide in ten years.  To tie the legendary Bryant, he would have to coach another ten years and average 11.6 wins per year...
