Here's how I wound up as a Yankee fan and a Jets fan.
I was born in the Bronx. My mother is a huge Yankee fan and was taking me to baseball games from the time I was 3 years old. By the time I was 5, I knew the entire roster and was reading every Yankee box score and the daily reports from the beat writers. Box scores being "Yankee numbers" and daily reports being "Yankee stories." (That's actually how I learned to read: the beat reports.)
I'm not even sure I was aware of football's existence, except for the Super Bowl. Cowboys-Steelers is the first one I remember watching. As a 5 year old, for me, the entire sports world consisted of baseball, the Knicks, and Michael Jordan.
The 2 years later, we moved in with my new stepfather. He, and his entire family, were huge Jets fans. I became more aware of football, and was now surrounded by Jets fans. And not just in the family. My new home was on Long Island. And that was pretty much it.
I distinctly remember early days when I would wonder why my stepdad hated Neil O'Donnell so much. I remembered him from the Super Bowl, and if he had been in the Super Bowl then that must have meant that he was really good.
Little did I know.
So there you go. Yankee fan. Jets fan.
