The only issue that made me hesitant to want him is his injury occurence. But he's been healthy this year. He hasn't missed that many games and 1 or 2 were taken for personal reasons and not injury. So ignore the number of games missed because they weren't all due to injury. In fact, he's been healthier than Galchenyuk, Gallagher, Shaw, and Markov this season.
I would definitely try to get him as a rental. If we do, I don't think we'll overpay simply based on MB's comments that he won't give up his top prospects for quick fixes like a rental.
I'll maybe try to sell Arizona on taking Pateryn and Desharnais + a 1st or two 2nds. The reason I add a 1st or two 2nds is to entice Arizona enough to take both players (especially DD). It might be the cost for getting him off our hands.
I'd trade for Hanzal in order to get first dibs at attempting to re-sign him to an extension.
He checks off a lot of boxes for the Habs...solid 2 way player, can log a ton of minutes, wins faceoffs, plays with an edge (when he's at the top of his game).
I've more than warmed up to the idea, I think Hanzal should be a prime target for the Habs.
