Well I feel that 6 years is a fair timetable to look at to take the past, present and future into account. In the past Six years my team has won 1 World Series Championship, 3 American League Championships, 6 American League East Championships, 6 American League Playoff Appearances, 1 Cy Young Award Winner, 1 American League MVP Award Winner, 3 100 Win Seasons, and 31 All Stars (Some Players Counted Multiple Times because of Multiple ASG Appearances). You guys on the other hand only have 1 World Series Championship, 1 American League Championship, 0 American League East Championships, 3 American League Playoff Appearances, 0 Cy Young WInners, 0 American League MVP Award Winners, 0 100 Win Seasons, and 20 All Stars.
And even if what you claim in your post is the case, it still doesnt hold water. We've heard Yankees Suck chants for years. Before 2004, that's for sure. All through the Yankees recent dynasty run when they were winning championships the chant was still around. So what was the justification and reasoning for it then?
