On Tuesday Boston lost a man who gave his entire adult life to the city and had one of the greatest impacts on one of the world’s most famous sports franchises. Former Boston Celtics player, coach and broadcaster Tommy Heinsohn passed away at the age of 86 on Tuesday. He was a part of the Celtics in some fashion during each of their 17 championships, the first coming in 1957. Heinsohn may be gone, but the imprint he left on the franchise and on the city is something that will live on forever.
