Tbh, the one area where many Finns are not impressed at all about the NHL is the coaching and player development. Many people believe that there are way too many inflexible dinosaurs who inherit their tactical and personnel management ideas from the ancient times.I hate to say this, but a teenagers who has not played in the NHL view of things matters not at all. Kakko's game would have led him to be a superstar.....in Liga. In the NHL, he would have been an also ran. With the coaching staves help, he took his game and then changed it to what works in the NHL. It looks like it is working out for the best.
And I think Finland is pretty used to maximizing the last drop of talent from our often quite mediocre teams agains much stronger opponents on international level - we have developed coaching to pretty high level. This is not a comment on Rangers coaching though of which I know next to nothing, Quinn certainly is no dinosaur and you have such a great depht of talent developing. Kakko's development has seemed pretty fine - I would have preferred him to start at the AHL to get confidence and time to acclimatize to the North American style of hockey, but on the other hand if you learn to swim by being thrown into the deep end you tend to learn pretty damn well.
