It just goes to show how little basketball coaches do outside of putting the right combination of players on the floor. He shows up for the first time ever with his new team a few minutes before the game yet he can run the offense as a PG.
Basically. These guys have been doing the same thing since high school. Other than verbiage, many coaches run the same sets. Either a team wants to run or slow it down. Not too much of splitting atoms there.
