Barkov asked to play in the NHL on the pre-draft interviews. Tallon picked the guy and the organisation let him play top line minutes. He has nothing to complain about (except for better line mates maybe). Hopefully they get to fix that this off-season and we can see what the guy can do surrounded with capable players. Much like Mackinnon this year.
So nothing there to worry about, really.
People here are taking his comments way out of context. He basically just said that the atmosphere is so great that it eclipses NHL regular season. And add to that, he ended his sentence in "this season" so there is more to come in his mind. He didn't say that the atmosphere sucks in Florida, he just said that in Tampere when the team makes the Finals, the atmosphere is great.
He hasn't once complained about his linemates either. Not to start the season, not at the end of it. But more than once I've heard him giving credit to his linemates on the goals he scored.
If you were Tappara fans on top of being Panthers fans and were at the arena, you'd propably agree with Barkov on the atmosphere part.
And Barkov, at least in his rookie season, has seen Tappara home arena quite empty and quiet. It happens when you don't play for a top team. That's propably one of the reasons why he felt the atmosphere was so special in the arena that he said what he said.
