Virtually nothing.
Ethan Keppen (if signed and if not returned for his overage year)
Arturs Silovs (who technically is in the AHL this year, loaned to the Moose)
Arvid Costmar (if signed, which seems unlikely right now)
... are the only possibilities, and Silovs as the backup goalie is the only one that's really likely.
You typically get the 2019 and some late birthdays from the 2020 draft headed to the A. Or some college guys from 2018.
2019 top 2 guys, Podkolzin and Hogs will be in the nhl. Focht already there now. And they have ncaa guys like Malone and McDonaugh returning to the ncaa. Aside from Keppan there’s no one from 2019 who is scheduled to go there.
2020, Persson the Swedish Dman from round 7 could make the move but he’s likely better moving up a level in Sweden. Think all of the other European players remain there next season as well.
2018 class don’t think there are any lingering ncaa guys turning pro.
maybe Karlsson comes over. But given that he hasn’t reached the top level in Sweden I doubt he would make the move over.
