The Celts are my all time favorite team in any sport. It was nice watching the Celts and Lakers go at it in the 80's (I still hate Magic for that baby sky hook), but for some reason, I don't feel the same anymore.
I am happy for them but it's just not the same. Maybe it's because they don't have a 'real' rival right now, I don't really know. Tomorrow they will play the Lakers, and even though the Lakers are good, I don't think they stand a chance.
Lately (last 15 yrs lol), I've been a homer. I live in South Florida so I love the Dolphins, Marlins, Panthers, and Heat.
