Went back to find Pronman's prospect report for the Stars, yeah, didn't have much to say about any of our European prospects. It's from September 2019, so I'm sure a lot has changed. For example, he still has Saw Peterson as a bubble NHL'er, had Back as his highest rated prospect (8) behind the likes of Gleason and L'esperance, and said he was a good two-way player, but not a good skater. At the time of writing we still had Stenqvist in our pool, he and Karlstrom didn't even rate top 20 and apparently that means they aren't worth even writing a paragraph about. I've found he underrates a decent amount of our prospects, but nothing ever egregious. Probably the nature of scouting countless players and being more conservative than a fan would because he has no vested interest in their succeeding. His September 2020 update doesn't mention anyone other than Eriksson as far as Euros go, and he isn't even ranked as an NHL'er anymore.
Wheeler did a January 2021 update and has Peterson as a tweener, skilled for the SHL as a top 6 player, but not enough for the NHL, without having enough all-around acumen to be a bottom 6 NHLer. He's at the end of a tier with guys like Damiani, though that was pre-AHL breakout. The Top 5 are all the legit prospects we are interested in, so no surprises there. Just for fun, Eriksson is dead last in his prospect list, and I think it's out of deference to where he was drafted more than anything.
