While I agree with those who would say that later starts are better for tailgaters and on-campus recruiting (due to Friday night HS football), as someone who lives in Colorado and is enough of an in-game psychopath to prefer to watch the games by myself at home rather than having to self-censor or embarrass myself in public, I love the noon (10:00 AM here) games. I get up, exercise (if I'm reasonably motivated), tune in, and have the rest of my day free by 2:00 or so. As far as competitive advantage or disadvantage goes, without looking it up, I don't know that OSU has an especially great record in home night games against decent opponents.
