Well, I've explained this many times in the past, but I'll do it again. I had moved to Brooklyn back in '87, and I became a fan of the Yankees in '88 (back when Mattingly was playing). The team wasn't that good then, but in New York they are crazy about their baseball teams, so I got swept up by their fanaticism. I moved back to Los Angeles later, and became a fan of Lakers. That's why I like some of the teams in L.A. and some in N.Y. After Raiders moved back to Oakland, as a form of protest I started to root fo the Jets, even though recently I started to root for Raiders again.
Not sure why I have to explain why I like certain teams, though.
