I find this refreshing as well. It's not like this isn't common knowledge. I'm glad a GM is being open about it, even if it's anonymously.
I think this could be Ainge. A big part of the article was not being trapped in the middle ground of first round playoff fodder or just missing the playoffs and getting the 13th pick in the draft. Among all the "tanking" teams, the only team that fits the criteria is the Celtics. Unlike the other tankers, the Celtics could've still been a solid team if they had kept Pierce and KG. The other tankers were already bad to begin with.
Plus, Goodman is a local guy and maybe he had a direct, face to face chat with Ainge.
