I believe the term “Green-teamer” was coined by the Sports Hub’s Michael Felger a few years ago as a way to label overly optimistic Celtics fans. The net has widened recently to include anyone who doesn’t bitch about this team’s flaws within seconds of uttering complimentary analysis. You know, someone who applauds 53 wins and an unexpected #1 seed without immediately belching, “But they’re still light years away from Cleveland and Golden State. Grr…”
Long-time Boston media troll Dan Shaughnessy was quick to jump on this bandwagon because a) it’s what he does and b) it’s easy.
