Says who? A person in a foreign country doesn't need classes, he/she needs one-to-one private lessons every day or at least three times a week. Of course the situation has been tricky because he has been with the Oilers, which meant long road trips and also with the AHL team, which meant he wasn't in Edmonton at all. However, his agent told the Finnish newspaper Helsingin Sanomat that it wasn't about the language.
Jesse Puljujärven agentti: ”Tämän tason pelaaja saa sopimuksen tunnissa vaikka 30 joukkueeseen”
The agent Lehto says in that interview as follows:
"When a 18 years old kid went to Edmonton, it was a challenge. Should have been able to speak and understand better. Ability to communicate wasn't at the level where it could have been"
"On the other hand, the language wasn't the problem in years 2 and 3. It's unnecessary to highlight that".
According to the agent the problem was the vagabonding. That back and forth traffic between NHL and AHL messed up things.
"It's not question about bluffing. Jesse has been and still is convinced that he wants a change. He is a NHL player"
"A player who plays at this level gets a job from 30 teams in one hour if he wants to. The issue is not that he couldn't get a job in Europe. It's about other things."
"Yes for sure it needs to be a oneway contract when we talk about a player who is at this level. But the question is here that we get a fresh start, a new opportunity. Money could almost be whatever."
Btw, how trustworthy is the Edmonton media? They might be fabricating things or setting up some kind of fake news. Especially this guy who writes those "9 things" lists, seems to be a very annoying person. It's all about rumors what he writes. He doesn't even bother to interview Jesse like at least the Finnish media is doing.
