IMO Grundstrom and Liljegren are both very likely to be impact NHLers, with significant upside. After that, I think Borgman has a good shot to be a quality 3rd pairing type.
Sandin, Durzi, Engvall, SDA, Bracco, all have shots to become NHLers, but I’m significantly less certain about them than I am about Grundstrom/Liljegren/Borgman.
Interesting that our top 4 prospects (IMO) are all Swedish (Grundstrom, Liljegren, Borgman and Sandin). If you count Johnsson as “not yet graduated” (just 17 NHL games so far), then our top 5 are all Swedes! There’s even an argument for Engvall being next. Don’t know if there’s much to read into there, but interesting.
