I feel too much like an overconfident messageboard fan when I say this, but if Barry's coaching is losing the team and would affect incoming/outgoing free agents, then it would be better to place the D with a caretaker, be that promoting someone we've got or bringing in a fired HC/DC.
I consider that a white flag for the 2023 season, but if it keeps our players from fighting each other, I'm okay with it. Maybe if everyone thinks he's a nice guy who juat isn't getting results, I'd understand running out the string with him.
