I remember becoming aware and taking quite a liking to the Cs when Larry came aboard. As a young Irish kid from a lower-middle class family who loved hoops, I had no other choice when the options were Cs, Lakers and Philly. Though it was hazy, the Philly battles stick out as the springboard for my obsession. By the time '84 rolled around I was a full-time fan, but the obession started in '85 when Kareem cleared the room by dominating in the Garden in Game 6.
It wasn't til '86 that my bedroom walls were COMPLETELY covered with Celtics paraphernalia. In fact, as soon as I could figure it out, I printed "duplicates" of all 16 banners using the "Print Shop" feature on my Apple IIgs (pre-Mac, people). Those hung proudly.
I saved every box score and press clipping from my local newspaper (the Times Picayune) during the '87 season thinking I was assembling a championship scrapbook. The '87 team remains my favorite and probably marks the apex of my obsession with all things Celtics. The guts that team showed was amazing. With the injuries that we had, we had no business beating Detroit or taking two games from the Lakers, and we were on Magic baby-hook away from going back to LA up 3-2. I still can't watch game 4 when it replays, just can't do it.
Needless to say, I stuck with this team all the way through to this day. My championship scrapbook was put on hold for 21 years, but it's been completed, and I couldn't be happier.
