-2 on the whole year isn't horrible, especially if there was a run of injuries that affected things. When Faber was merely eating minutes, to get us through games, that was useful too.
Personally, I felt that the 4 nations tournament was too much for Faber with his responsibilities on the team. I thought he came back looking drained, more so than Boldy did.
I do think Buium will help, but I still see a logjam at the position. I'd really like to see a Jiricek-Brodin pairing, and a Buium-Spurgeon pairing. That leaves Middleton-Faber as a pairing that has been successful in the past. I think with those pairings, you could probably just role the pairings and give them pretty much equal time.
This will help Faber with his minutes and probably give him more in the tank as the season goes on. There is also the possibility Faber simply went through a sophomore slump and will be better next season. Remember, in '24, Midsy had a pretty bad +/-, but he rebounded this season.
