Sam Poulin could use a fresh start.
He'd be an interesting swap. Not sure if he's got quite enough "value" straight across...but we're honestly talking about struggling "change of scenery" type guys anyway. So fiddling around with late round picks or something to balance is almost not worth the time of day.
And at one point at least, Poulin projected as more or less the sort of piece the Habs would probably look for. Good size, gets around alright, at least projects to be able to play a solid responsible Bottom-6 game. Plus, bonus Quebecois.
I'm a little iffy on Barron to the Penguins though. I'm not sure it's a foregone conclusion that Karlsson
can be moved in the offseason. I know the
want to is probably going to be there, but actually making it work could be tricky, with the sort of season he's having and that shambles that is his defensive play at this point.
So ending up with Letang - Karlsson - Barron down your RHD, seems problematic if they
can't move Karlsson. Barron is really more in that same vein, more offensive-minded guy who really needs to be on the Powerplay, if not the Top Unit to likely find his footing in the NHL. In theory, he's got the tools to be more of a two-way guy, but doesn't seem to have the mentality to do so.
But i do think he's a good "buy low" change of scenery candidate. His runway is running out in Montreal, and he's never going to see the top powerplay there with Hutson around, plus others.
