This is very logical. Every team in Denver should run. Because of the altitude, the Nuggets are wasting a huge advantage if they don't run.
Mike Malone, who is a pretty good coach, will coach a basketball team to suit it's personnel and do his best to win games. So, his teams will push. At first, he will push just to get them started. In 3-4 years, when they have good players in the right parts, it should work well.
The roster we had last year was not suited to play the pace and space game that Vivek, PDA, and Mully wanted. We didn't have the shooting or players to run that system. Moreover, Malone correctly believed that slowing down the tempo would help transition the defense from a nightmare to good.
It seems that the front office told Malone, you're winning games, but if we're going to be great, we need to shoot more 3s and push the ball more. Malone thought those guys were wrong and kept with his game plan. Malone was right about the style of play and the input being stupid.
