I just don't understand the concept of staying in Liiga to grow one more year. There's not a single player who's been NHL ready after one year in Liiga. Every single time they still need seasoning in the AHL.
You can do the same type of growing (or better actually), play top 6 minutes, learn the game in the AHL. And possibly get some NHL experience to boost your morale. As a young player you get these "ah i see this is what it takes" feels the closer you get to the NHL. Staying in Finland you get none of that and you'll still be as clueless the year after vs next year.
But overall i guess one more year in Finland wouldn't hurt that much (for Pulju he has to learn some english
). Anything beyond that is just detrimental in my opinion.
