GSW management expect Curry to be back on Playoffs so I think this will be fine as he can still recover at that timeline since he will set out at their remaining games.
There's no latest update yet regarding his injury, hopefully, it's not serious that he has to be out for awhile or will require a surgery.
They can't ruin this opportunity, they are now playing healthy with KT back in the lineup, so I would say they have a huge chance to return in the NBA Finals again.
If Curry will totally miss this and came back late on playoffs then most provably his team will struggle and this is another unfortunate thing will happen again on their team this season. Hopefully we can see those stars back in action since they are the main flavor on playoffs.
They will struggle for sure, Klay Thompson and the rest of the players can't win, at least that's my own perspective only.
