So long as he doesn't forget to do the other things that make him NHL-worthy (hitting everything in sight, crashing the net, solid defensive play) I think the goals will come. No, I don't think he will ever be a 30-goal guy, but that's okay.
One thing I'd like to see McGinn do more is actually create traffic/screens in front of the net. He can crash the net, sure, but one thing I found disconcerting this season was that without Landeskog, we didn't really have much in terms of presence in the slot, and there's simply no excuse for that kind of play with a roster that loaded up on grit the past few seasons.
This isn't in McGinn's defense at all (Quite the opposite in fact.), but he did come in a bit out of shape. He played ok, but a touch below his abilities while also going through being snake bitten.
As for the teams ability to create havoc around the net. Early in the season Landeskog was concussed, and O'Reilly was gone. Even then for a little while after Landeskog returned he wasn't bringing as much physicality. As well as the fact that Jones is and was, crap.
So I think McGinn contributed to that part of our game failing but he was still hungry around the net. I think he wants to be a goal scorer so he was focused on shooting instead of fighting for rebounds.
The last 5-10 games it seems like hes learning to balance it out a little IMO.
Also, I was wondering if we'd see McGinn improve as the season went on baring any major injuries, and he has. That says to me that conditioning was a factor as well IMO.
This stuff is just kind of an under the radar positive on the season though. There are still quite a few things that point to McGinn having the upside we seen at the end of last year. He's showing some ups and downs but some improvement as well. Which means he's learning instead of a 'You get what you see' type of situation.
I'm still hopeful that he can learn to be a 25+ a season guy consistently with a few 30 goal seasons.
