I didn't say coaches don't matter; everything matters, team talent, coaching talent, desire, facilities. What I meant was, in a football program with a successful past, there will be slumps, but there is enough inertia from past success to propel through the slumps to see success in the future.
When I was younger these were called "rebuilding years." Few seem to have the patience for such times now. I was born in the UT hospital and have been a lifelong fan, and have never been ashamed to be a fan. I just hope we don't start booing our own team, throwing things at opponents, or anything else that would bring discredit to ourselves.
