Hitting the advertisers is a great idea, perhaps a boycott of them will help shake things up. I have only been to a couple games the last couple years so I'm not sure who currently advertises in the stadium. I know Val's used to but I think Runza replaced them. Perhaps those of you who have been there lately can list some of them for us.
As far as replacement coaches, unless the person who bungled the last coaching search is removed I don't see how we can expect anyone better. Most of the "family" is getting up there in years, Gill would probably be the best candidate in that respect. I'm not against going outside the family as long as it's someone who will embrace the program instead of having a "one game, one season" attitude. Bob Stoops wasn't part of the OU family, he in fact is a Hayden Fry disciple, but he succesfully revived the OU tradition.
