Nuggets coach Mike Malone. What is the key to development now in the NBA? Malone: The easy answer is allowing young players to play and, more importantly, play through their mistakes. That’s what we’ve done. We don’t have a G League team, so we have guys that have all been given a chance to play and grow up and get game minutes. Right now the biggest challenge we have this year is Michael Porter, who falls into that young guy (category), he really hasn’t played in two years.
