That's what Damien Brunner thought as well
He thought he's a star and doesn't need to change his game. That's also why he ended in NJ and finally didn't get a new contract despite scoring a decent amount of points...
Honestly, you if you're trying to make the step from Juniors/Europe to AHL/NHL you have to adjust your game. I wasn't surprised to see Keller do well for the national team but fail miserably with the Coyotes last season as well as during the prospect tournament lately. Unless your name is Pavel Datsyuk, you can't skate past everybody if you're playing against men on a north american rink. Keller needs to get stronger and think the game quicker. He needs to be willing to adjust his junior game or it's not gonna work out for him. I've seen it happening to others before. List is pretty long. Just think about Linus Omark for example. Gifted like crazy but never gonna make it in NA because he's not willing to adjust his game.
