We've seen the team try to run and pass more often. I felt they were trying that at the start of the season, but it lead to turnovers due to players have poor spacing and not the greatest passing skills. Malone saw this and tried to limit tunrovers in any way he could. They still turn it over a ton though, and it gets back to spacing. In other words, NO SHOOTERS.
Pop grinded it out when that was his personnel. After seeing the Kings, Mavs and Suns, he changed styles over time. However, he only changed once he got the players to change. When he got Manu and Parker in the same year, he got the speed, ballhandling, shooting and passing he needed. I don't doubt Malone would do the same if the personnel actually fit.
The problem is the personnel guy doesn't understand the right personnel is needed to run.
