And it hurt him late in his career.
The way he's played since coming into the league was years beyond anything the league had seen. Inventing new moves and creativity. He played a style of only threes or drives and a method to his madness that had advanced stats people drooling. Knowing the midrange shot is inefficient. Gunning a three in every 2 for 1 end of quarter end of half situation. Taking open threes regardless of when during a shot clock it was cause in his view it's about what's my chances of getting a better shot not how much is left on the shot clock. He saw the floor and passed with incredible wizardry. This is what gave him confidence to tell Pop this is what I do. It's also why his teams always wins. Him being on your squad means teaching players moves like Eurostep, floaters, he single handedly made Parker a better reader of the floor. He knew in his mind about efficiency and willingly came off the bench because he knows he will get more touched in a condensed period of time and less minutes was not as important as touches. He also knew this put him at an advantage playing against subs etc. I also don't think Manu works that much during the offseason. All his skills are instincts vision intelligence and skill. He's not a workout guy or someone shooting till they close the gym. He's a pure intelligence based player.
His rationality and logic is also why he's atheist. He runs a math club as his charity I mean that's how logical and numerical he is. Manu would make a great GM but long story short its why he's failed.
Duncan is a dreamer. He believes regardless of age or situation it's possible to win a championship.
Manu approaches the game purely looking at odds. "Chances are we won't win 3 straight at home" "yeah I had a good game but probably won't play as well next game". "Really Game 6 was our opportunity. It's not likely to get 2 chances." Because he's so sure about why you win and why you lose it doesn't hurt him as much to lose cause he's rationalized it. He thinks it's good enough. He thinks we got unlucky in Game 6. He isn't as eager to win a championship cause he knows the difference even if we had won tonight would be sheer lucky play / bounce and not real difference between being Miami or SA right now. This at ude is why he is who he is but also why he can't go for the impossible.
