Honestly Pop was always successful and had one of the longest streak of success in any sport that I know of and 5 championships in about 20 years is something to be proud of and he never missed the playoffs and also had one of the most insane records with 50+ wins per season for the longest time.
However, even with all of that, Pop has always been a great human over everything else, he has always praised players character more than the talent, if you are not a good person you would have hard time with Pop, he cared more about the human than the player almost always. Which means they may miss the playoffs and he will not hold it against his players, he will of course try his hardest and yell as much as he can during the games but the moment the game is over, all players are like his children.
He instill discipline to the team, that's the level of coaching he has that is why he is very successful even if the big 3 have already retired.
Under his coaching, players will improve as no special treatment or favoritism when he is coaching the game, even if you are a star but if you don't contribute and do your task, you'll be taken out, that's how he is, that's why he last until now as one of active oldest coach in the NBA.
This is where technology will be tested, I have no idea how this is done but I would certainly like to witness the first game of the season resumption and hope the experience is good with the technology being adopted by the organization.
