I don't think I've seen one player who is clearly NHL ready at this tournament but I could see a few who will be with another off-season.
If I had to be on one player being able to play adequate top 9 or top 4 minutes tomorrow night it would probably be Kaprizov followed by McAvoy, Chabot, and Eriksen-Ek. Hischier might be an interesting gamble. Larsson hasn't looked great, but entering the tournament he would have cracked that list, same with Strome. Alex Nylander is putting up ridiculous numbers in this tournament, but he also isn't putting up numbers in the AHL that scream for an immediate call-up.
Last year at this time though the only guys who could have walked into the NHL at the close of the tournament and play well in the NHL immediately would have been Matthews, W. Nylander and obviously Pasternak. Nylander got injured but was practically ready and only had a 10 or so game stint in the AHL before being called up and having a strong tournament. Matthews plays the type of game and had the skill where he could have easily translated last year, and Pasternak was an NHLer at the tournament.
