Kidd is the Defacto DAL GM

[SkenfromLMF]

 The problem I have with your argument is that you agree Cuban is at fault but then turn around and blame Kidd also. 

Anyone who has been in management knows that when certain things keep repeating you look for the constant there. There was a poorly defined hierarchy even in the last regime. The GM was butting heads with another guy the owner had brought and the superstar was mocking the coach asking if this new guy was making the lineups. It was so bad that the real GM walked away in the middle of draft night.  Think how big a cluster that is. Does any other organization act like that?

This predates Kidd Now Kidd comes in and if history is repeating itself with hierarchies that are not being maintained then there is no collective blame. If you really are interested in a solution blame only the person who has the power to make a change here. That person is Cuban.  

The constant is Cuban. The one who can make a change is Cuban.  That is even assuming you are correct.  Nico might just be a terrible GM. What do we really know of his talent evaluation?   He never found any gems for Nike. From what I remember he was assigned to work with stars that were already in the fold.

Not the first time this has happened in the last 20+ years of Cuban ownership.
The PREVIOUS GM was so dysfunctional that he was at the draft and had to beg Donnie NOT to draft Podkolzine when he found out his power was revoked. 
Now I do appreciate mark as an owner, he is exponentially better than Ross Perot Jr and Frank Zach the Hack. But the new has worn off, the Championship trophy has tarnish, and mark is not above reproach or criticism. Heck at this point, well lets give this trade a chance - Not much faith in this working, but anything can happen.
