You must not have paid much attention to my posts as I've always been a strong proponent of GF/on ice & GA/on ice which is different from +/-.
Is it any wonder that he plays it safe with how the coaching staff utilizes him? It's like they want to coach the offense out of him, kind of like how Daley was handled as a young player.
But yeah, in a 6-5 game with 5 D I do consider it significant that he didn't get scored on. He consistently moved the puck forward by passing to forwards' tape to exit the zone. He kept the play to the outside when it was in his zone. He didn't flop around on the ice or take stupid penalties. More games like this and his confidence will start to build. Of course the last thing that should happen now is pair him with Oleksiak, which means that is what will happen.
I think it speaks volumes that in a game with only 5 D he played only 18:30 and everybody else was clocking in over 25 minutes of ice time. He was sheltered throughout the game and the fact that he didn't get scored on is not so much indicative of his great play but that he didn't play often against anyone of substance.
You are presuming they are trying to coach the offense out of him. If you have anything more substantive than that I'm sure we'll see it in the form of quotes from the coaching staff like we did with Daley. The way I see it is we have a player who is supposed to drive the play from the blue line, which if he did might earn him some PP time, but that has routinely given very little hint of offensive prowess in regular season NHL duty.
Injuries aside, if there is one defenseman who has shown that he might be a useful addition to the PP it's Nemeth, not Connauton. And as to the "flopping around taking bad penalties" comment, I'm assuming you're talking about Daley. Guy scored two PP goals and was the victim of a ref blocking an outlet pass, a puck going in off his skate as he tried to guard the back door, and made the best of a bad situation with a funny bounce off the glass. All in all, Daley was one of our best players last night any way you slice it.
Lastly, of course the rookies will be paired up. They will be played against lesser competition and sheltered just like Connauton was against Philly. I expect to see all of the top 4 logging 23+ minutes.
