He took them to the conference finals in back to back years. http://www.basketball-reference.com/teams/PHO/
A coach who had the benefit of a very, very talented roster. NY doesn't have a real PG, great long range shooters or athletic big men. You can't run and gun when you have no guns. Nate Robinson, Zach Randolph and Eddie Curry are not Nash, Amare and Marion by a long shot unless you are comparing their defense.
My mistake. So, I will rephrase the answer as "Guy has never even made it to the NBA Finals, so what would he be 'exposed' as?"
i dont buy into his "system" it seems more of a product of nash. according to his system it should make everyone max out their potential scoring ability but his two seasons without nash were very poor not even just poor denver: 14-36 phoenix: 21-40 those are terrible percentages I dont see him as a good coach because he needs to have players adapt to his system and not the other way around. He should be able to adapt his system to the strengths of his players. he is as stubborn with his offense as JVG is with his defense. at least on defense you can make players play better based on effort....cant really make a guy who isnt very good offensively better on effort.
What evidence do you have that he tried to run the same system in Denver and Phoenix pre-Nash? They changed their "system" after Nash got there. They decided to play small and run teams to death only after Nash came. After the Shaq trade, they modified that. There's nothing that says he's going to try to play the same way regardless of the roster he has.
