Before his "lost" 22-23 season, he probably was the most highly regarded domestic goalie in the KHL, he started all the games for the '22 Silver-medal winning ROC squad.
That said, he didn't play for a year and then put up decent but nothing special numbers and a losing record in the regular season and 1-4 playoff record for a sorely disappointing CSKA squad in the KHL this past season and then got crushed (small sample size on tanking team, granted) in his brief NHL stint.
I get that the Flyers are in no worry of a cap crunch the next few years, but this seems like a ton of blind faith for a guy you can't really say has "excelled given the circumstances" or "brings great veteran moxie and experience" or any of the other platitudes usually associated with tanking teams signing role players to larger than expected but short-term deals (ala the Blackhawks).
You really have to assume that the Flyers coaching staff and pro scouts just are absolutely enamored with his physical traits and think there is really, legitimately high NHL goalie upside here.
It's crazy that Ersson, who is very talented and despite some rough patches, has shown spurts of real NHL upside already in 63 NHL starts, got 2x$1.45 for the next two years but then Fedotov got over twice as much for the same period. Is this a sign that the Flyers are committed to running with Fedotov as the starter over Ersson next year, despite having barely seen anything?
