I voted for Gio here, I'm not arguing against him.
My post wasn't about specific players, it was about how we evaluate them in general. The original poster I quoted was criticizing the discussion for focusing on points instead of defense, because they believe defense should be the priority for a defenseman, but I think defensemen should be valued on their contribution to goal differential regardless of how they go about it. Lots of goals are scored for both teams when Brent Burns is on the ice for example, but the outcome is still in his team's favour. This is more valuable than a stay at home defenseman who limits goals against, but whose team rarely scores when he's on because he can't move the puck.
With Gio, his offense is up near the leaders so it shouldn't matter at this point. It would be a more interesting question if he had, say 25-30 points.
