ABU DHABI, United Arab Emirates — The Nuggets dropped both preseason games against the Celtics this weekend in the Middle East, but unlike the competitive and largely encouraging first matchup, Denver lacked energy and rhythm Sunday in a 130-104 blowout Sunday. With Michael Malone resting multiple starters, the rematch was more focused on evaluating second- and third-unit players before the Nuggets’ long flight home and subsequent week off between preseason games. The results were mixed.
