You clearly don't understand how American sports leagues operate.
The relegation system doesn't matter? Are you kidding?
For instance, do you know that in American sports leagues, the teams at the bottom of the standings purposely lose games and fight to get last place to get a more favorable spot in the next seasons draft? It's actually beneficial if they are closer to the bottom of the table.
And have you heard of the term "Load Management?" That fucking concept doesn't exist in European football.
In the PL, almost EVERY match matters and there's a sense of desperation. That includes teams at the bottom of the table because of relegation.
