That's what I mean by 'not being bigly into sports so maybe that explains it' - perhaps I should try it some day, but the 'what you can't get at home' experience of a stadium just doesn't appeal to me, personally.

Obviously it does to some people, I didn't mean to suggest that stadium-goers are idiots who don't realise it's objectively better at home! I just meant 'game-watching' - but even there, sibling commenter to you makes a point about the rawness of physical contact if you're close-up in the stadium.
