The Denver Nuggets used to be one of the best fast breaking teams in the league. During the George Karl era, the team utilized the altitude at Mile High and ran their opponents in the dust killing them with transition points and making them beg for oxygen.
However, ever since the end of the Karl era, the Nuggets have noticeably strayed away from the fast paced basketball that they found much success with during the days where they were a permanent playoff fixture. This is something that should change if they are truly serious about becoming a contender eventually.
