I've seen him 3 times this year, although in fairness the third time with Sarnia I wasn't paying much attention to the game.
And Painchaud... I have to say I'm disappointed. I bought into him as a late-round hopeful for the draft last year too, as many did, based on limited viewing. But in similarly limited viewing this year, I'm seeing regression if anything. I don't know if I'm just seeing the wrong games, although his stats don't tell a very reassuring story either.
I would say that his head just doesn't look like its in the game. You could say the same a bit last year too, of course, but still, one would have expected progress. He skates well, he looks like he has added some strength, but he seems pretty ineffectual overall. Every once in a long while he'll do something, make a rush that makes you realise he has the physical talent to be a frontline player in the OHL, but then he finishes it with a bonehead pass-away or just skates off into the corner and lets the play disintegrate. He doesn't seem to use his teammates very well. And he vanishes into the ice for long stretches. He should be a much better player, but something is going wrong.
I wouldn't project him as an NHL prospect at this point. He has some of the tools, but I think the best you could hope for, at a stretch, is that he completely turns things around, really puts in some serious effort for the rest of his junior career and a few years in the minors, gets a mean streak, and emerges as some kind of quick 4th line defensive player. But even that's so hard to see right now.
