I had no idea about this.
While Corso may say somethings that are just ridiculously inaccurate and is kind of annoying on the NCAA games, I do like him and reading this article about him just makes me pull for the guy. He is no where near as infuriating as Lou Holtz (at least in my opinion) and I love his tradition of picking the winner of the big game by putting on the helmet/mascot head of the winner. It's always good to be picked against when it's him because usually he picks the loser.
Reading the article, the scary part is the swallow test where he has to find the right word to describe where he is at. It's scary that something we take for granted like speech and the ability to think and make connections can be taken away so suddenly.
Here's rooting for Lee Corso.
