A local very successful football coach in these parts was fired after, among other things hitting one of his assistant coaches with a cane. It was basically the beginning of dementia.
I thought about that. Lute Olson, here in Tucson, went through some very public shenanigans before being asked to step down as basketball coach. He seems to have righted himself, now.
I think that Pat Summitt, had games where she was totally out of it, before being diagnosed.
