Yankee fans

A-Rod is the greatest shortstop in baseball history. When he went to the Yankees, Derek Jeter (a mediocre defensive player with limited range) insisted that he had to continue to play short. A-Rod moved to 3d base and the Yank's defense has been weaker than it should be.

Ever since Jeter's selfishness (which continues to this day), the Yankees have failed to win a world series.

Yankee fans have responded by booing A-Rod unmercifully. Of course, the Yankee fans treated Mickey Mantle like dirt for the first 10 years of his career (the majority).
