I'm gonna simplify this right now.
All Antoni does is make sure he has shooters on the floor, tell his guys to run, run, run and take the open shot no matter where you are on the court (good 3pt shooter or not).
Then he needs a good to great PG out on the floor with court vision to make ALL the on court decisions, including where people should be. (essentially pushing ALL the ancillary coaching duties onto the pg)
This "offense" is no different than a youth league! The only difference is you probably won't have a great PG at that young age yet.
