Rask is now the only one left from the golden generation of Finnish NHL goalies. The list could look really bleak in a few years:
Saros
Lankinen
Rask (I'd guess he has 3 years left max)
Korpisalo (needs more consistency or he'll find himself in the KHL)
Koskinen (Edmonton is a terrible fit for him and that may screw his chances with another team, he's also getting old)
Kähkönen (Seattle's number 1 soon enough)
Husso (same boat as Korpisalo)
Raanta (injuries and age, I think he goes back to Europe in a year or two)
Luukkonen (hopefully he's Buffalo's answer in net)
Gibson (probably Europe bound, he's toiled away in the minors long enough)
Vehviläinen (don't think he'll make it)
Kaskisuo (already signed in Europe)
Annunen (tough to say at this point, he's just starting his AHL years)
Worst case scenario we have 4 NHL goalies in 2023 (Saros, Lankinen, Kähkönen and Luukkonen).
