When talking about his offensive awareness? Yes. I don't see those totals going up much more unless he starts doing more than what he's been doing: skating it in for a close shot at the goalie or immediate pass backs to the point. Again, just because I see limitations doesn't mean I'm calling him crap or even the worst defender we have offensively. Frankly, you can probably build some pretty good offensive set plays around Nurse doing the above.
But to return to the post that started this: that doesn't mean he has the offensive awareness to do the things the article mentioned he wanted to develop: slowing the game down in the offensive zone and finding reads/seams in play. That's an entirely different skillset than he's shown so far and is something almost no player develops after a few years in the league. Almost all the best passers/offensive players demonstrate this in some capacity from the get go. It's possible but unlikely. I'll be super impressed if he can add that element to his game.
As I said a few times, however, I could see him upping his point totals if he could develop a big shot. The rebound assists would definitely help his totals.
Edit: one such play I'd love to see is Nurse temporarily taking a winger slot in a play after a rush. He consistently just gives up the puck after he gains the zone in part, I think, because he wants to get back to his designated spot as defender. So why not have, say, a play where RNH covers for him at the blue line after Nurse is on the rush with McDavid, and let Nurse take some more time to either find McDavid or try to get a cleaner shot off in close.
