Four .500-ish teams playing at a sub-.450 clip and all but one team playing under .500 ball isn't folding? I don't feel like this is a difficult concept to grasp but apparently it is. Here's my point, clarified: If you have eight .500-ish teams with two months to play, you'll usually end up with a few of them under .500, a few of them will remain around .500, and a few of them will end up over .500. And that's ignoring the potential improvement some of those teams will see by making trades to shore up deficiencies. For all of them but one to remain under .500 is a statistical fluke, one you do not see very often in baseball (again, 2017 is the first time this century the AL has ended up with just five teams over .500 and it even happened in a 15 team league, not the previous 14 team league). It requires a lot of teams folding to end up at that number, which is why we haven't seen it in at least the past 20 years (I stopped checking at 2000).
