Is there a poll backing that? I don't get why any of the middle of the pack teams fans would love this format. It's a never ending cycle of pointless games because they will never win. Just because they all do it doesn't mean it's the best thing either.Hundreds of millions around the world like pro/rel, so you're outnumbered.
Many US soccer fans follow other leagues, generally because they or their parents came from those countries. They're used to it, support it, and find it odd that the USA, with its emphasis on rewarding success and punishing failure in most things, doesn't follow that practice in team sports.
I personally only watch our team and team USA.
