We've all gone through argument. When the Mets are doing better than or beat the Yankees we try to rub it in the Yankees fans' faces. And the answer always comes back: The Yankees have 27 World Series rings. How many do the Mets have? Well a few years ago I realized that this argument is very flawed , and historically the Mets are just as good as (if not better than) the Yankees.
Now as we all know, the Yankees have been around for a long long time. Most of their championships came before the Mets existed. To compare the last 52 seasons isn't fair. This being because how can you compare a team that's been around forever to a relatively new team? For this reason we must compare each team's first 52 seasons to each other. But, there's one catch. The Yankees' early years were before expansion, when there were only 16 teams in the league. Now there are 30. That's like almost double! Which makes it twice as hard to win the world series these days. (In addition to this, until recently the National League had 16 teams which makes it even more difficult.) Now, the Yankees were established (as the Highlanders) in 1903, but they spent the two years prior in Baltimore as the Orioles. So, when their second World Series came around, in 1927, they were in their 27th year. And when the won their third World Series, in 1928, they were in their 28th year. Since it's (almost) twice as hard to win these days, the Mets, who just played their 52nd season, are ahead of schedule. By my count they will stay ahead of the Yankees until 2015 if they don't win another World Series and if they win one before 2017 they will regain their lead.
So the next time a Yankees fan throws this argument at you, you have a response. And if they find holes in this theory (I highly doubt it) you can always tell them that they're stupid.
