The New Orleans Pelicans went 0-3 last week and yet wobbled very little in NBA power rankings. Three losses against superior competition should not be terribly surprising. As long as the Pels can continue to pile up wins against the dregs of the league and teams in varying levels of dysfunction (although the New York Knicks are trying to set a new land speed record in that regard) it appears they will continue to stay afloat in the race for the playoffs.
Since Jrue Holiday returned (November 18th) the Pelicans have been a perfectly average NBA team.
