I don't see much in the way of FO change this year. They don't have to succeed on ice because this is a "rebuilding" year and, like
@VladDrag said, none of the beats will call Tortorella out on icing a non-rebuilding lineup. They will almost certainly cool off throughout the season but this will likely devalue players who should be moved at the TDL, so I am expecting "We didn't get any interest in what we thought X is worth" to justify only minor roster changes or maybe even a Walker signing.
As for losing the room, to whom is Tortorella going to lose it? The vets he is overplaying?
