Bottom-5, easily.
Molson, if he's shortsighted, probably don't want that to happen, but if he understands how good teams are built, won't mind 2-3 years in the basement. He will reap rewards after that. (unless a major shitstorm happens, like MB thinking that trading prospects and picks could help our 'rebuild')
Price will still be there in 2021, Weber, Drouin, Domi, Gallagher, Lehkonen, Kotkaniemi, Juulsen, Mete... add Brook, Poehling, Ylonen, Primeau, Olofsson, Fleury, and a couple others to that, plus the ones we'll draft in '19 and '20...
Of course, no one can ask the players of a team to lose, they won't agree anyway. But add 'plugs' like MB did this season (be it purposely to 'tank' or because he really think he reinforced the team, whatever) while waiting for the kids to develop properly, it should happen naturally.
