I read an article about Pops coaching (specially young players) but I think it applies to vets who are new like you mention in this context that includes an approach of military training. How untrained soldiers are put in the most ish of situations to see if they can work and figure things out togehter. Who steps up, who takes command, who starts to scream and blame others etc. Basically setting up the young cadets for failure, you break them down then you build them up. Surely goes with Pop's military background.
Otherwise what do you make of him taking the opportunity Tim the absolute center of the Spurs universe on defense is out and he goes and faces the GSW and gives a lot of minutes to Anderson and Simmons, puts Simmons on Curry, does a whole lot of weird stuff. CLE, same thing, although his hand was forced by LMA early foul trouble. I think this is a trial by fire and guys are getting much much better.
Batmanu posted a tweet that Tony said communication was much better this game, a big factor in our terrible defense the past few games without Timmy.
