I haven't seen this article posted yet, so I thought I'd share:

It's interesting because it confirms what a lot of us have complained about Schultz: for an offensive d-man, he has no long-range shot to speak of. No big slapper, no one timer, no point shot. All he's got is his wrist shot, and he's trying to sneak in to use it far too often. This leads to his being out of position on defensive plays and being unable to keep the puck in at the blue line (though he also seemed to fumble the puck a lot there...). It also, as the article mentions, means that our better in-close shooters (our top-end forwards) aren't getting the chance to shoot instead.
Honestly, his lack of shot options is what worries me more than his lack of grit, as has been focused on in this thread. As someone else mentioned earlier, he's never going to be Chara or Weber - the kind of top-end d-man he should be hoping to emulate is Nick Lidstrom or perhaps Karlsson. These guys might not be super physical, gritty dmen, but they have/had a wide range of tools and this is a big part of their great play. Justin does not have all that many tools - he has a wrist shot, pretty good passing, nice skating, and pretty good offensive awareness. If he doesn't expand the tools he has available, I'm skeptical he'll ever amount to more than a number 5 PP dman.
