Personally, I think Jeff Green affected Glen. I think he did because Glen was the number 1 option before Jeff came and the bench was just new and had to go through a lot. Well, when Glen lost his confidence in the offensive end he looked like he stopped playing D, that's what it seemed to me. I just hope that Glen just accepted to be a defensive guy and let Jeff be the go-to guy, i don't know. They just didn't have chemistry, the bench.
It also affected the chemistry, obviously. Like Doc said, the timing but we can't really trade Perk early because he was injured.
Personally, I think the Celtics have something left and could win it next year.
