Laine is the biggest wildcard this year. He could be all over the place. And I'm not sure what would actually be best for his career. If his total is too low, he could basically end up anywere in the fututre, if it's too high he could end up being forced to sign a long term deal in Columbus which would be terrible for his fututre. The best option might be somewere inbetween were his totals are pretty solid but ultimately Columbus sees it's best to move him at the trade deadline.
Another big worry is the coach Brad Larsen, as he's the reason Laine got benched and there could be some bad blood between them. This could mean that Larsen won't use Laine to his fullest potential and try and ruin Laine's future instead.
But lets say Laine gets to play on the 1st line and 1st powerplay all season with Voracek actually feeding him somewhat successfully 35+ goals shouldn't be impossible. Laine could even be able to set a new Columbus single season record in goals. At least Laine might get a good start to the season with Arizona Seattle and Detroit being the first 3 opponents and they're all terrible teams this year. And then following it up with Carolina and Dallas in the 5th and 6th game of the season, who Laine has had some success against during his career so far. Only Islanders will be a bad fit in the first 6 games as Laine has been terrible against them.
