My brother is a hardcore Patriots fan (since Tom Brady was a bench warmer), and our entire family are NY Giants fans. You may not know this, but NYC sports fans have a strong rivalry with Boston teams--New England, the Red Sox, and the Celtics to a lesser degree. I remember when the Patriots lost their winning streak (zero losses season) in 2007 in the Super Bowl to the the NY Giants. We talked so much shit to my brother for a good year. lol. But at Thanksgiving and Christmas, he is that Cowboys like fan. We have to sit there and hear the "but where your Giants at?" forever. lol.
