Where it may be coaching is something like this: "Oh, they're playing defense against us this way... Let's try our "counter A"... and then "counter B"... I don't see confidence that there's a "Ok, we got a strategy for that. Let's see what they do with this."
On the other hand how much can a coach do when the problem is fundementals - boxing out, passing back out and re-posting when double or triple-teamed inside, protecting against 3-pointers, driving and dishing, driving to get fouled, not getting beat on the break, keeping both arms up defending inside.... and so on. These are things that have been stressed in practice, surely.
So... head scratcher...
