One thing to note is that - precisely because it is so low-scoring - football is the most "unfair" of the big team sports: the one where the objectively weaker team has the best chances of winning.
And yet, at least at the club level, it is also the most unfair because money is allowed to rule the game, and 99% of national titles are won by about a half dozen clubs (or less), across every league in Europe.
I've always wondered about that. Doesn't it get boring to be a fan of a team that has no chance of ever winning?
I wonder the same about fans of teams that win something every year.
(Besides, Bayern's defeats always seem to matter much more than their wins because they're unexpected and the wins are not... really, I can't get into the minds of people who're into that. What makes them tick?)
But yeah, the closed leages and salary caps and drafting rules exist in America because the sports they watch wouldn't be bearable otherwise. Football really didn't need all that til fairly recently, though really by now we're in dire need of reforms in that direction. It's all the Champions League's setup's fault, of course.
(Incidentally, the Football League was always far more closed and thus 'American', the tiered divisions notwithstanding, than the Serie A let alone the Bundesliga.)
