i know someone who's a patriots fan in football, yankees fan in baseball, and duke fan in basketball. i mean geez.
My business partner is a "diehard" LA Laker, NY Yankee, Dallas Cowboy, ND football, & Duke basketball fan. Grew up in Florida & graduated from Wake Forest. Not even joking.
I'm a Panther/Bobcat/Yankee/UNC fan. Grew up in NC & graduated from UNC. Those have always been my teams. Panthers are the only one I follow religiously, though.
Became a NYY fan when I was 9. My family & everyone around here are Braves fans. I found it annoying & when the NYY beat their ass in the WS I fell in love. Been a fan ever since.
