Watched all three U18 CZEvSUI games, didn't pay much attention to the Swiss though, so take my post with a grain of salt.
My thoughts are that Ustinkov is legit, he caught my attention in every single game. Not sure he has very high NHL upside, but I would have him as high as the 2nd round. Reber is fun to watch, but unless he grows, I am thinking more of mid-rounds for him. Curious how he does in Sweden, but at 5'10", he would need to dominate to be a top 100 prospect. And then of course the goalies looked good, all seem to have fine physical tools too, so there is likely at least a draft pick in there as well. The rest of the team looked solid, some good skill here and there. Wouldn't surprise me if one or two players took the next step and became also legit NHL prospects throughout the season, but since I didn't focus on the Swiss squad, I can't really give any names here.
