Javonte Green shot 5-8 from 3, 19 points (+21), in the second half. Duncan Robinson was 4-5 form 3 and 18 points (+20), in the second half. How often do you think these 2 will combine for 37 points in a half?
I get that this kind of collapse is a scene we have all watched too many times. It happens to all teams. I am not sure if it happens to BOS anymore than average. I think it is a biproduct of taking a lot of 3s. If you take more 3s, you will miss more shots, and those misses tend to lead to better looks at the other end for the other team. And if a couple of guys get hot and hit a bunch of 3s, it can go bad fast, faster than if you took less 3s.
I don't agree necessarily that this means that BOS should stop taking 3s (yes, the core debate every time we lose a game like this). A good 3PT attempt is still a good 3PT attempt. You will have stretches where you miss 3 or 4 in a row and this feeds the run for the other team. But you might also have a run where you take it to the hoop 3 or 4 times in a row and come up empty. Either can be the right approach if you are taking what the defense is giving. Either can be wrong if you are forcing it. I don't agree that it is as simple as "we missed a few 3s, call a time out and change the gameplan". If it was 3-4 forced 3s, yes, call a time out and reset, but that does not necessarily mean change the whole gameplan.
