Thanks to Anonymous Hero for the getting the quote off of Joe Morgan's chat as an ESPN insider:
Drew(San Diego): Joe, with the way the NL West is playing, namely 4 teams in the top 10 in ERA and a solid record against the other NL teams, has this division finally removed the label as the worst division in baseball?
Joe Morgan: I don't think they've removed all of the doubt but they are improved. Colorado and Arizona are a part of that, but I personally don't think the Dodgers. Padres or Giants are good teams. They haven't proven much yet
