At this point, time to move on.
Hart is a good but not elite goalie, he's 27 and if he does bounce back, his next contract probably wouldn't make sense for a team in a middle of a rebuild.
Ironically, his "suspension" helped the Flyers draft Jett and Martone, so he may have inadvertently speed up the rebuild by imploding the goalies.
Briere pretty much implied the target is 2027-28, when he said in his interview they are not looking at free agents the next couple years, they're more interested in cap space and a winning environment to entice their own players to sign extensions. "Maybe in 3, 4, 5 years . . ." that is, when they're competitive, he might look at free agency to fill holes, but not as part of the rebuild.
At that point, Hart would be 29-30 and very expensive if he rebounds to his former level of play.
I think the plan is go with Ersson and Vladar the next two years, with Bjarnason and Kolosov in the AHL and Zavragin in the KHL, then in 2027, when Zavragin comes over, re-evaluate. I was suprised they didn't draft a goalie this summer, but if he had a commitment from Kolosov to go to the AHL, he might have wanted to wait a year to avoid a logjam.
