You know your coach is doing well when people have to think about his hypothetical response to coaching a hypothetical team of completely different players to complain.
It's not a complaint though.
Let me give you some more context. When I think of inflexible coaching strategies, I think of Kurt Rambis.
If we all dust the cobwebs off a bit, we should be able to remember when Kurt Rambis came back to coach the Timberwolves from '09-'11 and tried to run the Triangle offense with a team that was absolutely ill-equipped to run it. The Wolves proceeded to go 32-132. He followed Phil Jackson to New York, tried to implement the triangle again in '15-'16, went 9-19, and has subsequently never coached an NBA team again.
Some of the best blogs from the time have gone under, but you can still read some of the coverage
here or
here or
here- in short, Rambis obviously didn't think that the triangle was the problem. I doubt he does today, either.
The glaring problem, obvious to mostly everyone else, was (and is) that the triangle requires players with a particular skill set
and an NBA with a particular rule set to be as good as it can be. Rambis trying to run the triangle with Jonny Flynn and Kevin Love is the definition of a square peg round hole - surely if you have a great pick-and-roll point guard and a great pick-and-roll power forward you want to run a PnR-focused offense.
But Rambis's inflexibility absolutely hampered that team (and arguably did a serious number on Flynn's career). I wonder if posters here think Joe is that dogmatic about his offensive approach.
