They were predicted to be any where from the worst team (most analytic sites) to a playoff team. A prediction of a "bubble team" that has an outside chance of making was not a consensus nor a common theme. Even if it was, its fairly irrelevant to what Murray expects.
Last year when asked about the playoffs he said (paraphrasing) ->
he would never rule it out but its a long shot. We would need a lot of things to break our way.
Before this season, one of many comments about expecting the playoffs or that its a realistic goal for the season (not an outside chance)
“I’ve said to you guys a lot that we just want to improve every year and I think we have done that to a pretty good degree,†Murray said, via Sabres.com. “So that will be our statement to the players that, yes, our goals is to make the playoffs and we actually do expect that we can do that.â€

For a GM thats pretty straightforward I find it kind of funny your dismissing what he said as GM speak.
