I think this is a pretty outdated view of NBA coaching. NBA coaches aren't like college coaches (which is why most college coaches crash and burn in the NBA). The best coaches, from Phil Jackson on, install a system, plug in players that they can trust, and then take a hands-off approach for the most part. The martinet, call plays every time down the court coach is a thing of the past. Every once in a while a coach tries it and he doesn't last. Boylen comes to mind.
Also: our "undisciplined" offense was the best in the bubble until it ran into a Lakers team that has a fantastic defense built around two all-league defenders.
This is the thing about Stotts: he's actually been amazingly adaptable in his time with us. When we've had the personnel, we've had really good defenses, even with a backcourt of Lillard and McCollum. But this year, on top of Lillard and McCollum, we had lead-footed Whiteside and old-as-dirt Melo. Pick who you think is the best defensive coach in history and see if he can make a silk purse out of THAT sow's arse. So what could he do but try to maximize our offense? And seems like he did a pretty damn good job of that, given our limitations.
