You don't get it. The best basketball is played instinctually. Players have a foundation of fundamentals and technique and they know how to react to any situation without having to take a second to think of the reaction. They just react. Amare is very much this type of player. Many of his flaws stem from a lack of fundamentals, technique and discipline, aspects that he was never held accountable for developing, nor ever taught to him by his coach. I was never surprised when Amare made as many "WTF?!" plays "HTF?!" plays. he simply was never taught to adhere to such in practice (largely because a D'Antoni practice was a glorified scrimmage and not an actual time of learning), and without the hours of practice to develop right habits for his instincts to rely upon, he simply went with whatever reaction came to him first. On defense, most of the reactions were errors in judgment, not that he ever knew any better, nor that D'Antoni ever cared.
That's what I mean by "not thinking" ... it means having a game that so based upon what's been taught and pounded home during ones development that once in a game, the right reaction just come as second nature. No thinking required, just a reaction based on fundamentals, technique and discipline.
Amare NEVER got that under D'Antoni. He was little more than a finisher like Spida or someone from the And-1 Mixtape Tour. D'Antoni's entire offense was opportunistic. It wasn't based upon anything solid. It's the reason why a good defensive team could stifle them enough to evoke frustrated forcing of shots or drives, many of which resulted in an offensive foul by Amare.
As a compe or, all Amare knows is "GO!" If you add any hitch to his go, you increase the risk of mistakes exponentially. If Amare's reactions aren't based upon right aspects of the game, or your philosophy makes him question his reaction for even a split-second, or you lack of a foundation makes him force the issue, you're going to see him make/commit boneheaded mistakes, unnecessary defensive and silly offensive fouls.
Why I think Amare's at ude now is so important is not only is he speaking with excitement on the topic of defense, but he may very well have the support system in place to better his situation through the development of fundamentals, technique, positing, patience and discipline.
Of course it's not going to come together all at once, but Amare, despite being a loudmouth and a bit of an airhead, is a player who's proven to pick up on aspects of the game very quickly when they are properly taught and/or points of emphasis.
Porter and his staff may be the fuel for Amare's fire.
