I became a Braves fan because of the TBS thing. I used to watch TBS all the time b/c of WCW, the cartoons and the Andy Griffith show, so I adopted the baseball team as well before I even knew they were good. Even with them leaving TBS, I'll still be a diehard fan.
With the Nets, I grew up a diehard Knicks fan with a casual interest in the Nets, but when the Knicks traded Patrick Ewing, that team became dead to me, and I officially switched to the Nets.
I've gotten into so many Starks arguments over the years. I hate him. Even moreso then I hate Zo.
I was raised a Saints fan. I have casual interests in the Giants and Jets from growing up in NY. If the Saints ever move, I'd probably become a Giants fan.
And with hockey- I just am a fan of the Leafs and Canucks. Can't really explain it, I just love both teams. If I really had to pick one, it'd probably be the Leafs from living in TO for the last few years
