I imagine nearly all of us watch a lot of CFB on Saturdays, some of which may involve games where we don't care who wins much. I rather enjoy those games. I can pay attention to "details" and try and learn what is going on better than if my team is playing, or even if two adversaries are paired off and I have a dog in the fight.
I personally am not crazy about wide open offenses, at least not for long. But there are some teams I enjoy watching, mostly because they do more with less and are tough teams, or I admire their coach, or something.
Kansas State - great coach, clean program
Michigan State - usually a bit down on talent but Dantonio makes the most of it
Wisconsin - old style trenches football with deception and passing thrown in
Northwestern - kind of like Vandy, but better, and often a very tough out even for top teams
Stanford - kind of like Wisconsin in a way, but somehow found some talent lately
Memphis - a non-P5 team that can play like one
If K State is playing say Iowa State, I'd guess few of us cares who wins, but it's a chance to watch football and not get hyperventilated.
