Opponent is always going to matter for fan enthusiasm, no matter what time the game starts. Florida was a night game, Weber was day. I wouldn’t draw any conclusions so far this season.
However, I have noticed that my viewing habits and excitement levels are different watching the games this year. We’ve been stuck with night games for so many years that I’ve had to try a find a new gameday routine. I don’t have time for a round of golf in the morning, get some things done during the day and then tune into the game at night hoping to get to bed before midnight.
At the same time, I remember years ago when all the games were noon or 1pm starts and being able to generate plenty of enthusiasm. So I think it comes down to not being used to day games instead of any intrinsically better by playing at night. If NFL games played during the day can be raucous, I don’t think college should be any different.
