Don't get me wrong, I've been on the PLD bandwagon since he was drafted. But he really needs to step up his game.
Jet's management will choose Dubois right now over pretty much anything else, cause of the cost it took to get him. They traded a good middle 6 C and the heralded team savior Teemu 2.0. He almost has to pan out. But right now it looks like CLB won that trade, and that's mostly because of Roslovic.
I'm not concerned that much. It's good for Roslovic, because he was never going to have a chance to be in the top 6 in Winnipeg, in Columbus he has a shot. Although, he started hot and ended up as a healthy scratch by season's end. In all likelihood he'll produce around 35-40 points a season in his best case.
The Jets got what they needed though once Dubois starts playing as the 1B he should be. I really liked Laine, but Dubois makes the Jets a better team than Laine did. At least in theory, if everything goes as it should and then the Jets have easily won the trade.
For right now, there is probably nothing reasonable that would make the Jets trade Dubois. They have no reason to move him when everyone thinks his value is low, so if someone seriously wanted Dubois they would need to pay full value, there would be no discount. They struggled for so long to find a top end 2C, they aren't going to give him up based on a small sample size. It's not their MO.
