I have football on my mind a lot, and I don't even understand the game. I can't imagine running through scenarios and players and schemes 100% of time time, especially when all anyone cares about is the three or so hours on Saturdays. It's gotta be brutal to put that much time into something and then when it's not executed how you imagined getting a shit storm of criticism from the fans/media.
FWIW. Michigan doesn't seem inclined to get re-involved.
