30 Days, 30 Teams, 30 Facts: Boston Celtics

This article is part of our 30 Days, 30 Teams, 30 Facts series.

With the NBA on hiatus for at least 30 days, I'll be coping by posting an article every day with 30 random/interesting facts from each of the 30 teams. Hopefully, the season will resume when I hit publish on the Wizards' article.
