I don't get this opinion. Just look at all the stats. He gets power play time, but most of his points are 5 on 5. He is also clearly our #1 Dman based on ice time (even strength and PP).
Marincin has the benefit of Petry, who has been proven to make his partners better. Petry is in his prime, so he's the perfect guy to transition the young Marincin in the league.
Schultz is young too. At 23 he is already out-performing Dmen like Brian Campbell at a similar age (and yet so many say he will never be his equal, lol whatever). He has had troubles, but look at who he gets to play with. It's been a carosel of bottom pairing Dmen, and whoever gets the Schultz assignment ends up looking bad because Schultz has the hardest assignment on this team by far. He soaks up the most minutes because he has the best puck skills on the back end, and so the play goes through him as much as possible. Unlike Marincin or Petry, he's not allowed to focus on defense because he has to take risks to produce offense, which he does. At the same time, it means that he racks up some minuses, particularly when your partner is playing over his head and for much of the season the goalies couldn't hold up their end of the bargain.
Schultz needs a real partner. Hopefully it's either Marincin or Klefbom, or even Nurse. Ference, Fraser, and Larsen aren't cutting it.
Well what I mean by PP specialist, is offensive D-man, I'm just used to using that term for all offensive D-men. As for minutes played, I couldn't care less, because he's playing way too much and he clearly can't handle the ones he has now.
You do have a good point regarding Fraser being his partner, however Andrew Ference is an NHL D-man, maybe not at the expectation some fans had but he's an NHL defensive D-man so if Schultz can't play with him....there's room for concern. I'd really like to see how he performs with Marincin, because although it didn't work in their first game together, I think cutting Schultz's minutes next year and playing him with Marincin could be an incredibly awesome third pairing combo that would allow J Schultz to develop his D and focus on offense.
Corsi wise, he's at a crossroads in terms of comparables. At his age, he compares with Carlson, Marc Staal, Hamonic, Alzner, and Hjalmarsson, all who have pretty nice track records at the NHL level (although keep in mind, these guys are all heavy on the defensive side of the game).
He also compares with Myers, Ryan Wilson, Sbisa, Luke Schenn, McBain, Bogosian, Del Zotto, Jeff Schultz, Theo Peckham, and Jack Johnson. All who have major defensive deficiencies or question marks.
A good portion of those who performed much better at a Corsi level than Justin are stars on D in the league (Calgary has one developing right now with TJ Brodie) so with Justin, you can kind of see the potential and risk level with signing him to a big contract right now. There are many D-man who at Justin's age simply performed a lot better. Whether a new partner fixes that remains to be seen.
