That's the thing. I said it last night but this Celtics team is poorly coached. No real coach would let their team take random 3s like that. I get defense is good so things might shift up a little, but it barely looked like the Celtics (and sometimes the Heat) were running plays that they had thought of before hand and practiced. It was more like they were just professional basketball players who had played together before and received some form of coaching. Very mismanaged.
You compare this to a god-team that does mesh well together like the 2014 Spurs and they liked 3s, yeah, but they had plays and positioning and passing to get the open looks they wanted. Didn't feel like that with the Celtics.
