The problem in looking at singular stats, is it often ends up with biased results. Should we expect Benoit to have the same xGF%, with 75% dZone starts, while Rielly has 36% dZone starts?
It's the same with forwards... Holmberg at 19% oZone starts, while Nylander is at 59.8%.
Usage matters. Quality of competition matters.
Meanwhile, Benoit also has the second best ACTUAL GA/60 of D on the team, and we are a positive in GF vs. GA when he's been on the ice.
I'm not trying to make the argument that he's a great D or anything, just that we can't point to one data set to prove a point. In the end I agree with some of the comments above... if we think the 6D is the problem here.... I know we all want superstars in every spot on the team, but there has to be near league minimum guys, and you get what you pay for, more or less.
