Everything should be looked at in context. Generally speaking, if there is a young player preforming that well in that league, it is interesting. However, Cehlarik is 25, has little room to grow, and his performance isn't THAT impressive. Carter Camper has 17 points in 11 games for example.
Top European leagues are filled with guys who extremely talented, but perhaps are deficient in one area which keeps them from being NHL players. Cehlarik just isn't a good enough skater IMO.
Par Lindholm in his final SHL season was almost a PPG player (age 25 season)
Joonas Kemppainen score TEN goals in 17 playoff games over in the KHL in 2019.
Yet, we've seen how both of these players are the NHL level were offensively deficient, offering basically zero contributions with the puck from the blue-line in.
Not only is the talent gap between the NHL and European/Russian leagues great, the style of game is drastically different, especially when you factor in international sized ice that some leagues/teams play on.
The KHL is literally loaded with former NHL guys who got a cup of coffee at the NHL level but ultimately were unable to carve out a niche or spot in order to be a long-term NHL player.
Names of hockey luminaries such as Linus Omark, Nigel Dawes, Linden Vey, Peter Holland, Corbin Knight ,Jorden Schroader, Peter Regin, and Bruins legend Kasper "Dog-man" Daugevins were all among the Top 30 KHL scorers last year. Some of these guys were fairly highly regarded prospects once upon a time. Yet none of them could ever be considered legit full-time long-term NHL players.
