They found in reality that the vast majority of fans attending games and watching on tv changed their allegiance at least once over the course of their lifetimes. I suspect the same holds true for American sports fans. And in a multi-team city like New York there is a sizable block of people who root for all of their hometown teams. good points... in baseball, my "true" allegiance has always been with the Mets, but I've always had a secondary team...when Willie Mays was a Giant, it was the Giants with Mays/McCovey....that ended once Mays became a Met...when the Indians had a young team in the early 90's, with the speedy Kenny Lofton, I also followed the Indians until they couldn't afford to keep their players...when a Met would go somewhere other than the NL East or the Yankees/Sox, I would follow them...currently my secondary team is the Guardians since the trade of shortstops... in other sports, which nowadays, I almost never watch anything other than baseball, it has varied over the years... I was a Cowboys/Bills fan as a kid in football, losing interest after the Aikman & Emmitt Smith era, casually watching the Patriots/Packers mostly because I live in New England now and my son is a huge Green Bay fan...but can't really say that I've watched football in several years...in basketball, I was a NY Nets fan when they had Doctor J in the ABA, and then became a 76'ers fan after the ABA folded and then a Suns fan for awhile but haven't watched in years... as far as the NY thing...as much as I have followed the Mets over my lifetime, I can't imagine watching the Yankees, Jets, Giants, Knicks, etc...
