Given how he's playing right now, he doesn't need to get better. He just needs to keep it up. He's been really good for the Pack in the first 6 games in all 3 zones. In the past, he was very good in the middle of the ice, decent defensively, but as I noted many times, he'd look lost on offense and as soon as he'd cross the blue line, Hrivik would have a dear in the headlights look and caused a turnover. This is not NHL hockey.
Right now, he looks more confident on defense than ever, just as good in the middle, but all of a sudden, he's a real player inside the other team's blue line. What used to be turnovers now become scoring opportunities. We saw it at the end of last season and it's even more so right now. It's possible he's just hot, but it's not just a matter of the puck going in for him, he's actually making better decisions now. The points he's putting up is not just additional offense, it's more defense too in the sense that he doesn't cause turnovers. If he keeps it up and proves that an NHL team can rely on him to do this for 82 games, he will play in the NHL.
