Is that on Ty or is that on the players not being smart enough? I assume it is a mixture of both. It can be taught to an extent but I also believe there are some players who are not mentally capable of playing "smart" basketball.
Though BBIQ is always a limiting factor, I think teaching players how to react is the one trait that sets great coaches apart from the rest. Popovich has almost proven this beyond a doubt with all the players he's been able to insert into his system and get to perform at a high level. Same with Sloan's ability to resurrect careers almost in their graves. Getting players to react correctly in a consistent, reliable manner is the coach's #1 priority.
That's just an example of why he is considered as one of the best basketball minds in Europe. He is far more deeply engaged within the theories of the game of basketball than your average good coach would be and he actually can transfer it to the players maybe except the latest run of CSKA.
What I liked most about his philosophy is he says it's not so much which system you chose as it is executing the correct way. That tells me he can mold to strengths while remaining focused on the details that matter.
I also like his discussion of semi-transition, or secondary transition buckets. This is the easiest area to score in consistently, and something Ty never seemed to use (one of the reporters mentioned this to Ty??? during locker cleanout day and gave a supporting stat but I don't recall it exactly).
