I'm not so sure that is going to be the case if Toronto does manage to pull it off.
You look at Boston as a team, they're really not in "bad" shape. They're just a little light on skill up front.
However, they've got over $20m in cap space for next year, without a ton of major holes to fill. Yes, Debrusk is a UFA and Swayman an RFA; but that stil leaves space to make a reasonably impactful addition or two.
Plus, the bulk of their team is still very much on the right side of 30. Pasta 27, Zacha 27, Debrusk 27, Frederic 26, Geekie 25, Beecher 23, McAvoy 26, Lindholm 30, Carlo 27, Peeke 26, Swayman 25
