Maybe the jealously started in Philadelphia when the New York Mets, after just seven years in baseball, won a World Series. Meanwhile, we were down here sitting on almost 90 years of membership in the majors without a World Series win.
Maybe the resentment in That Town Up North started when Tug McGraw had no problem bringing his “Ya Gotta Believe” mantra of the 1973 Mets with him when he switched teams and applied it to the 1980 Phillies, whose fans conveniently forgot where they heard it seven years earlier.
Wherever it was, somewhere along the way, Mets fans and Phillies fans decided they just couldn’t get along.
