Let me interject something right here.
I consider myself pretty knowledgeable about the history of the Boston Celtics, though I didn't follow them until 1972. That means that I missed, and was too young to remember, the entire eras of Bill Russell and Bob Cousy. Nevertheless, the body of work of those two men I find simply FASCINATING! I read as much as I can about those two, especially Russell, who has to be the greatest champion in pro sports history. I worked with a teacher out here in California who was on the 1956 Olympic team with Russell and knew him personally (this teacher was track and field, not hoop). Even though I did not follow the Celtics closely during that era, reading about it and knowing about the heritage of the Celtics brings me closer to the team and to that time period.
I call upon you young people out there to be proud of your team, but also to read up on the entire history of the team, so that you too will be even more proud of the team you root for. There is no sin in not being born yet to have experienced some of the low moments in Patriot history. Just read some books (unfortunately, there aren't that many out there) and articles and you will gain a much better understanding.
And do not apologize for being young! Many of us wish we could be 20-somethings again!
