As far as watching the game on TV? The cheerleaders hardly have that much screen time, and I've never been one to drool over something that I can't have. So there won't be anything "missing" there.
Rowdy could kick rocks for all that I care, tbh.
I've been watching UFC for months now without fans. It was a bit odd at first, but hearing extra hits and noises, especially the trainers hollering, added a cool touch I didn't expect to enjoy.
I love watching football, I miss it as usual. So no, I'm not really going to miss the fan noise much. I look forward to the new experience.
