I know it is not their style but if I was the Carolina GM I'd be working the phones to get Laine. That's a team where every player is elite defenisvely so they can easily insulate Laine with 4 good defensive players on the ice at any point and let him do the one thing he does well... score goals. They are one of the few teams where Laine makes a lot of sense.
Jordan Staal line has like a ridiculous 70%+ xGoals but not that many actual goals. Just throw Laine on that line, even if their metrics drop to like 55% they'd still be scoring a lot more goals then they are now.
If I was the Carolina GM, I'd give up two 1st round picks, a 2nd, Drury, and Brent Burns (for cap reasons) for Laine at 20% retained.
Carolina gets a 35+ goal scorer if healthy for 3 playoff runs at $7million, to get over that playoff hump where they can never seem to score. Columbus gets a pair of 1sts, a 2nd, a good young player in Drury and Burns whom they can flip for more picks. And Laine finally has a chance to be a goal scorer playing on a team where everyone else is doing the defensive heavy lifting. It's a steep price to pay for Carolina and Brind'amor isn't gonna be too thrilled about how Laine plays but imo worth it for them to finally break through in the playoffs.
