I don't think that's it. I think Brown is over-coaching if anything. He tries to micromanage too much, he tries to detail them on everything. Not necessarily in games, but to me, the sense I'm getting isn't so much that the players aren't respecting/listening, it's that Brown is telling them too much, with too much specificity and likely too many contradictions or conflicting pieces of information. I think the team is probably _trying_ to do what he says, but finding that it's just not confidently or clearly presented enough.
That's the only reason I can think of for why a group of extremely well-paid and (typically) hard working professionals could possibly be this severely stunted.
If they weren't listening/respecting MB, then _at least_ we'd see some more free form play, _at least_ we'd see some more easy buckets or attempts to play blacktop style, it might at least be entertaining. Instead we're seeing hesitance, indecision, laziness, trepidation and overall timidness that, to me, seems more likely to be a byproduct of trying to be too 'perfect' or too close to some ideal that is too far away from who these players naturally are.
Phil Jackson is the greatest coach of all time not because he won a lot or was gifted immensely talented players, but because he understood that vital aspect of coaching that comes from both finding who your players are and letting them be that within the reins of your ideas. If they're not comfortable, they're not going to be effective.
Even Kobe doesn't look comfortable out there, he might 'get it' better than anyone else, but he is playing like he'd rather be playing a different style, like a jazz musician playing country.
