I think it's important to beyond stats when projecting how players will do in the NHL. Don't get me wrong, I love the points, but some players can make the transition easier than others due to their skills and physical talent. I find the biggest separator between the NHL and the other leagues is the level of athleticism. We just waived a guy, Pulkkinen, who scored like crazy in the AHL , but can't make a dent here. Our coach, Boudreau, was an AHL legend, but could never stick in the big leagues. Granlund is a legit NHL'er but nothing like he was projected to be judging by his play internationally.
All of these are examples of guys who weren't big enough, strong enough, or fast enough to make an impact in the NHL( Granlund still has a chance). Hope Kaprizov is able to. He doesn't seem to have any one athletic talent that makes him stick out. Tarasenko isn't big, but he's a beast, explosive, and has a great shot. Kucherov is highly skilled, and fast. Kuznetsov, too? OVI and Malkin are obvious HOF'ers...no need to mention them. All of this guys are bringing superior athleticism to the table in greater or lesser degrees. What is Kaprizov likely to bring? He'll never be big and have reach. Speed, maybe? Strength? Shot? Sounds like he doesn't excel in any of those areas in the KHL, just is an all round smart player.
