The video in the tweet below should be played to each and every Celtics player. The lesson is that if you don't have a real passion for playing in the NBA, and particularly for the Boston Celtics, perhaps you may want to think about another endeavor. This is a conversation between two of the most iconic Celtics of all time. Bill Russell set the tone, not just for the Celtics, but for the entire NBA. And I simply adore Kevin Garnett. Unlike Russ, The Big Ticket only garnered one Title in Boston.
