So you think packing up his bags and going back to the KHL was done because he thinks it's actually going to help him make the NHL?
Just for the record, I absolutely think this would more or less be the unanimous opinion in Europe.
Looking at a sample size of all kids traveling across the pond, it is hard to deny that players staying longer in Europe develop a lot better than those who go over early.
And there are certainly objective factors that explains why that is the case too. It’s extremely important years around 18-20. You can adopt and learn the small things when you are older, and many just seem to stop developing their skills when they go to NA early. You take attention from training to learning a new language, new way of living, new style of hockey, new size of the rink etc. And a player in the AHL will practice a lot less than players does in Europe. More games and more buss rides, at least comparing the SHL to the AHL the difference is huge.
Many SHLers will describe coming back from the AHL to the SHL as a downside being that there are so many practices, saying that sometimes in the AHL it felt like they just played games and travelled, didn’t have time to practice.
So to answer your question, yes lol. I definitely think that. There are of course rare exceptions, but the AHL has an awful track record of developing good NHLers when it comes to kids that spent a little longer time there.
