I'd like to see college football look out for the fans a little more moving forward. I know, probably a pipe dream. I think that starts with prioritizing traditional/regional rivalries.
And I'd like to see the playoffs mirror FCS more or less. Start rolling with them soon after Thanksgiving.
Almost all playoff games on campus (that's the coolest part when watching on TV, and also astronomically better for fans of those teams).
Maybe you have the Final Four (so two games) on New Years, followed by the championship game a week later. Although I wouldn't be against trying to figure out a way to play the title game on New Years.
And then play the championship game every year at the Rose Bowl. I know I am biased growing up as a fan of the Big Ten, but it's the best tradition left in college football. Embrace it. There is no reason to continue calling it the Cotton Bowl, Orange Bowl, etc. once those venues changed.
Play the title game every year at basically the same place and time (late afternoon kick in the Rose Bowl). And have it either on New Years or one of the first Saturdays after.
In my opinion, college football's post season lost a lot of its appeal once they moved title games indoors on Monday nights.
