Poulin is just playing out the string on an expiring contract that is unlikely to be extended. He's managed 15 NHL games in 5 pro seasons. So unless there was a pressing need for him in the A, that's just a roster move. So, it boils down to Jarry for Skinner, Kulak and a 2nd. Kulak is a bog standard stay at homer in the last year of a bargain bin contract. He's better than a couple of the Pens' options on the left side of their D, so ... cool. Skinner is Skinner and the Pens should be used to that since he's basically Goalie Ned with higher highs and lower lows ... and they put up with Ned for two erratic years recently. The key is that Skinner is out of contract in June whereas Jarry's equally unpredictable but less volatile butt is signed for two more seasons after this one. The (likely) middle of the round 2nd is the only asset the Pens are gonna still have come July 1, you'd think.
For Edmonton, this is a risk worth taking. Yeah, Jarry is all over the place but he's been pretty decent this season, hanging out on the plus side of the goals expected per 60 column for the first time in several years. But the Oilers HAD to do SOMETHING in net, and trotting Skinner out there like a real live starter was starting to drag their whole program down the drain. And even when Jarry is bad, he's nowhere near as bad as Skinner at HIS worst. And waiting to see if you could do better later sounds good if you're not the one watching your goalie sink your team deeper and deeper into the muck.
