I don't think we can or should bank on that, because one injury would mean dressing Brown full-time with no proven NHL depth beyond that now that Dermott has been claimed.
Ideally we enter the playoffs with this sort of formation:
Ek-Bouchard
Nurse-?
Kulak-Stecher
Emberson
I don't think Emberson could complain too much about being a black ace given he's never played an NHL playoff game in his life and is the clear #6 right now. Provorov, Pettersson, Andersson, Matheson, Carlo, Borgen, Murphy, Jensen, Ferraro, Carrier and Liljegren are all players I would kick tires on for different reasons. Even if none of them turn into an Ekholm-level player (and that's a big ask obivously) they all represent something different we could use for a Cup push.
