One thing that is pretty clear is Cuban is terrible at communication. You remember the Dragic trade confusion?  Who was the GM who they hired who quickly resigned and went back to Houston?  I can guarantee you Nico did not know he was only brought in to be the relationship guy when hired.   Then you had the Donnie/Bob V mess.   All leads back to Cuban being a bad communicator.  If you look at a lot of the problems the last 20 years it starts with that.   

It's not really about communication imo. It's a different level than that. 

The problem as I see it is that Cuban (a) has always seen himself as the smartest guy in the room, (b) has always thought he could do the NBA GM job expertly, once he got a bit of experience under  his belt, and © did not want to find, pursue, and pay for the expert to do expert-level GM things. But he would hire people to do some degree of GM-like things to essentially assist him. He seemed to infer to these guys that their would be the voice he listened to, therefore conveying authority, but he never really intended to let anyone else make the decisions. 

The guy you are thinking of is Rosas. But he was NOT hired to be GM, and in fact he quit once he recognized he was 3rd on the totem pole here in decision-making. 

Cuban never really intended to hire an actual GM to make decisions. He was always going to make the decisions - with helpers, of course, who may in some cases have done ALL the evaluation that was in a decision, but still it was Cuban ultimately left to do the picking between path A and path B. THAT was the problem, because he was just not as skilled in NBA GM things as he thought he was, and he made stupid choices at times that were MAJOR ones. (I think that's still the case, and what has him on his little rant tour against the Mavs, mad that he's not getting to make the decisions these days.)
