Is Blues defenseman Alex Pietrangelo a serious candidate for the Norris Trophy? I don't know the answer to that, because I don't know what the voters are thinking. But I do know this: Pietrangelo certainly is doing enough to be a strong candidate for the award, given to the NHL's best defenseman at the end of each season.

The list of other candidates figures to include Ottawa's Erik Karlsson, Boston's Zdeno Chara, Nashville's Shea Weber, Vancouver's Alexander Edler. And maybe Nashville's Ryan Suter.

Let's look at a few reasons why "Petro," at minimum, should rate for a spot among the three finalists for the Norris:

1. The Blues are on the verge of allowing the fewest goals per game in an NHL season since the league expanded from the Original Six in 1967-68. The Blues' GA/game average of 1.81 is better than the previous standard-setter, the 2003-2004 New Jersey Devils, who allowed 2.0 goals per game. And Pietrangelo arguably fills more important roles than any other Blues defensemen. So if your team is permitting goals at an historically low rate, and you're the best overall D-man on the roster, then shouldn't that matter when the voters examine Norris contenders?
