Honestly, I’d look into a guy like Lyubushkin, big RD that can play physical. Liked what he shown in the playoffs the last two years.
With young guys on D, he could insulate a bit on the third pair and keep the physical side alive. He’s also a good bet to trade at the deadline so young guys like Reinbacher, Mailloux and Barron will get a chance + a free asset.
If not Hakanpaa could be useful, but I think Lyubushkin is a better bet.
On offense Kubalik could be a bet that pays off. Adds a bit more offense in case someone is injured.
Matt Martin/Blais could be nice on a fourth line for size and more physical play.
