Why is it comparisons of physical guys attract so much heat anyway? The Sheary-Puustinen one was just as bad. Puustinen doesn't have Sheary's speed, and is less likely to gain it than DOC is a punishing attitude to physicality tbh. Doesn't have his playmaking either, although I think he does have a better shot. They were always intended to be rough examples of the archetype, as I said at least a couple of times either.
But fine. DOC doesn't have Foligno's attitude to physicality. I do think he could be as good on the boards, but that's a big shout. But to sum up DOC without references to other players -
I see a player who's big and fast, and fairly engaged and smart. He uses his body well but not punishingly; he goes to the blue paint, he's willing to take punishment to win races; he's effective on the board and on the forecheck, and has room to grow in both areas. He has no obvious issues in his own zone. In fact I see a sure fire NHLer except -
Where's the offence?
30-odd games on the 4th line is a very unsafe sample for assuming a guy has no offence though, so you go back to the AHL and junior and his numbers are those of a guy who almost always has some offence at the next level. You watch what he does as well and it's not just the process of a guy who was bigger than everyone else and now isn't. You look at his NHL highlights, you look at his attributes, he has the ability to blow past people and ability to get to the net that you will get you points and goals without needing to be great. His shot has beaten NHL goalies in pre-season. But at the same time, it's not coming together. Maybe his shot isn't enough for regular season goalies. Maybe the fact he's not great with the puck on his stick will hold him back (counterpoint - we've seen a lot of fast guys who aren't great with the puck on their stick get to 25-30 points regularly).
So the offence is the question.
If you want to compare him to other players - and noting once again that relying on one comparison is just straight up not worth the time of day as a point of argument -
Honestly Jankowski's career out of him would do great. Two good seasons then dump before he goes downhill. I think he's a lot faster and lot more engaged than Jankowski though, even if Jankowski's hands are better from memory.
You could use Derek Grant as another example of his build coming from NCAA. DOC's outpaced him pretty much since he was the same height at every level. I'd say DOC is faster and more engaged than Grant too, and would point out Grant has rolled out plenty of 30 point pacers for Anaheim.
Look at ZAR - once again, faster and more engaged (at least, more engaged than the ZAR that developed after realising he got injured every thirty games when he tried to play physical). Better at the same age bar ZAR's monster last season for Northeastern if I'm reading Randy right. ZAR did flirt a few seasons with the idea he could be a 30 point guy (never played enough games so we're talking point) before falling off. Will probably get there one day if he stays fit and is given the linemates.
Brandon Tanev is another interesting one as an NCAA player who grew late. For once Tanev is the faster and more engaged player, but probably not that much faster. DOC's bigger. I might give Tanev a slight edge of hands. Tanev at the same age DOC is now was headed for his last college year, but he's paced 4 seasons in a row near 30 points since finding his groove.
And Tanev makes me think of Lafferty, who's also a bit faster and more abrasive. Age 24, Lafferty was playing his first full AHL season. Didn't do as well as DOC by a long shot. Remains to be seen what he is, but I think he'll be a 20 point NHLer for a bit since Chicago seem to think it. I'd suggest Archibald as a strong comparable for Lafferty in terms of career path and archetype.
The NHL is littered with guys with his career path and some of his rough athletic attributes who found a good niche as a 2-way 20-30 point player. Those are just the Pens-centric examples. Add Hags as a premium version. Past numbers would project DOC to do better than a lot of them. There are probably plenty of examples of guys with his early NCAA and AHL numbers who didn't stick, but I don't have an archive for looking them up.
And tbh I'd imagine few of them would have his athleticism or defensive responsibility.
From this point he should be a near lock to make it. I don't feel super confident given the eye test but there's good reason to think there's a solid chance we'll look back and see growing pains.
Oh and re the Zohorna comparison - probably not a huge difference between them. DOC is faster, Zohorna a better puck handler. Which tbh bodes well for DOC, as if Zohorna can maintain the conditioning needed he should be an NHLer.
