I do agree with this, we can still win a series or two. Just can't see us winning it all. I do think this team right now without Svech is still better than 2018-19 overall. As potential underdogs/being written off too the team may play with that chip on the shoulder that we played with in '18-19. Honestly think we've been missing that the last couple years when we've been favorites in most series.
Yes it happens a fair amount, certainly not common or more than like 10-20% of the time but there are plenty of times "feared x injury" turns into "actually y injury that is still serious but not as bad."
Even just go back a year. Svech had a nightmarish postseason (5 points in 14 games). They still came within a game of the Conference Finals.
