Fact, at that point he had run his course and it was time. You know it's true.
As for his success, that is an interesting point and you are right, he holds that title. My issue or point if you will, he always had great teams. Some would argue the best in the country but would always come in "2nd" when he ran into a team of equal talent with a more competent coach. That was never going to get better. He was never going to stop running straight into the teeth of the D even when it was obvious it wasn't working. He was never going to recruit a real QB nor was he ever going to adapt to what CFB had become.
So yes, if you want to call me out for that, not only guilty but proudly guilty as charged, Les was here at least a year too many but can't change it now.
