People were saying the exact same thing about Makar and Heiskanen at this time 2 years ago as well. Fact is the U18s are one of the most important tournaments for the draft. Its the last big tournament before the draft and is often the best chance to see how these guys match up against each other.
Caufield is playing on a stacked team but if you watch the games, he is generating a tonne of opportunity all on his own. And its not just his goal scoring that has been on display this tournament but other aspects of his game as well. He's a good passer, a solid skater, and a very smart player. And while he is undersized, it has proven to not be an issue so far as he has not problem getting involved in the contact and actually initiates it sometimes. I've seen him throw a few solid hits against bigger guys in this tournament already.
To me, he has easily played himself into that huge tier of guys that could go anywhere from ~3-12 in the draft. Cozens, Byram, Dach, Krebs, Zegras, Turcotte, Podkolzin, Boldy, Soderstrom, and Caufield.
To me he's definitely a part of that group right now. Probably towards the bottom or middle of it but definitely in it and all it takes is Colorado, or LA, or Detroit being super high on him and all of a sudden he goes at 4/5/6 instead of 10/11/12. We saw it last year with Hayton and with Kravtsov. And we saw it the year before with Makar.
Another guy who has impressed me a lot at this U18 tournament has been Newhook. I was a big skeptic of his the last couple of months because he didn't really seem to take off offensively in the BCHL like I had hoped. But he's having a strong U18 and playing with his piers has shown that he's definitely got a lot of talent. Skating is the big concern with him and whether it will be good enough to be a Center at the NHL level, like the concerns around Jost now. But he's another I wouldn't have much concern with taking at #16 at this point and could certainly see a team or two taking him in the #10 range of the draft.
