Under the highly reliable Doug Moe +/- system, which ranks teams based on road wins vs. home losses, Denver is currently at +2. Only Memphis, with a +3, has a better Doug Moe ranking. It's very easy to be over critical of a team with a lot of early road games (the Nuggets play 17 of their first 23 games on the road), but the the Doug Moe +/- system keeps schedule anomalies in check and credits teams who are playing well on the road (usually a reliable indicator of who the better teams are).
