You need to leave the board now.
I have, on occasion, rooted for another team strictly for apparel reasons. Like I used to love the supposedly offensive indian on he Indians old hats. So I didn't cheer for them really, but I did have a hat. I also did almost buy a Red Sox cap once for a similar reason.
I have never ever followed another team. Sure I've chosed sides in the World Series, or even just wathcing a regular season game on TV though.
No second favorites in baseball of which to speak.
Championships for MY teams in my lifetime:
Cincinnati Reds - 75, 76, 90
Chicago Blackhawks - 10, 13
University of Kentucky - 78, 96, 98, 12
Cincinnati Bengals - None
Chicago Bulls - 91, 92, 93, 96, 97, 98
