I just think the problem is this core group. Is it a generation thing? The philosophy of copying the 2015 Warriors? Not tough enough? Bad coaching fit? All of the above?
Granted these were the Suns so a loss was inevitable, but man they got blown out and not only that they lost 4 of their last 5 road games in the West. The worst I have ever seen in a long time.
I've said this a bunch of times, but since you brought it up I'll say it again:
It is absolutely a problem that Boston has been trying to copy the Warriors. Why? Because the Warriors have maybe the two best shooters of all time, plus one of the best defensive players of all time. Those are not things you can duplicate. It works because of what they have; if you can't have what they have, then don't bother trying to do what they do!
I've said a similar thing about people trying to copy LeBron James teams, which usually featured a smallish lineup and no dominant center—
it's LeBron James. As much as I dislike the guy, I can't deny that he's a generational talent, and that's not something you can duplicate!
Teams need to find their own identity. The Warriors didn't copy anyone; they might've been a bit lucky to land Curry, Thompson, and Green, but they blazed their own path. Boston has to figure out its own path.
