Hofer hits UFA status in 2028. If all goes well, I more or less expect Hofer to get bridge type deals until around that point, and we transition from Binnington being the highest paid goalie to Hofer being the highest paid goalie.
For Neighbours, he's not getting a deal this summer, I think both sides see the value is seeing what happens this season. Blues don't want to lock in a long-term deal if he doesn't sustain success, and if Neighbours does produce like last season and even take another step forward, he'll earn more years and money.
I think personality wise, Neighbours would easily fit a long-term deal, I think the valid concern is figuring out what his ceiling is. If he hits 50+ points this year, I think a long-term deal is on the table. If he gets 25ish goals and 40ish points, I'd expect a bridge because both sides would still be pretty uncertain of what that ceiling ultimately is.
