If they can't make it out a weak North division then I do think they need to consider moving out a core piece. Kind of sounds to me like Leafs fans are trying to walk back the high expectations they've set for themselves.
Your first problem is thinking what fans think has any baring on what the team will do. Your second problem is trying to pretend any statement isn't subject to change based on what actually occurs.
If the Leafs lose round 1 and have sub .800 goaltending, it'd be hard to make the case that they should blow it vs finding competent goal tending. If Matthews/Tavares/Marner all get taken out game 1 from 3 dirty suspension hits, it would also be hard to make a case to do much of anything different. If they somehow get outplayed or embarrassed by any team in the North, than yea, time to consider bigger moves.
We won't know until we see what happens though so this exercise is a waste of time. It seems like a desperate attempt to get an early victory lap in before a single playoff game is even played.
