Great thread. TP's all around.
My first memory of the Celtics were the 1985 Finals. Back then, they didn't broadcast NBA games in Spain, so it was a report on TV of how the Fakers won in the Garden. As strange as it may sound for younger fans, we didn't have the Internet, so all info I got was from newspapers and the occasional TV report. Although the Fakers won in 6, I became a Celtic fan, and the next year I wanted them to crush the Fakers, but the Flakers just were too afraid to fight the Rockets, and you know.
Then the 1986 Draft came... and the McHale foot, and Bird's back, Reggie's death... and then Pitino. Through all those tragedies, always thought the Celtics are the best club even when they've had terrible teams. The Internet has made it easier to be a fan, so I've become a more die hard one.
The beauty of the Celtics is that you don't choose them, like they say, but you get caught in their charm even in their least brilliant moments. Reading the thread it's amazing how many of us became fans in losing times.
