1. MFYs Everything else is situational, relative, conditional. I can disdain any other team for a series or a season or a generation, but I can also drop a grudge if the moment moves me. Found myself admiring the 2011 Cardinals despite despising the 1985, 1987 and 2006 Cardinals. Couldn't hold 1969, 1984, 1989, 1998 and whatever passions arose in the heat of 2015 against the 2016 Cubs. I'm still down on the Royals and Utleys for 2015, but if they were to come up against the MFYs, I'd put those respective weeks of enmity aside in common cause, as I did grudgingly for the 1999 Braves (though mostly I ignored that World Series) and 2009 Phillies. Once upon a time, I couldn't forgive the Red Sox for daring to attempt to defeat the Mets at their pinnacle, but sooner or later you have to appreciate a bigger picture. Mets-Nationals was never much of a rivalry, but I did find myself happier that they fell out of the 2018 race than I was distraught over the rising fortunes of the Braves and (for a spell) Phillies.
