Last time Curry faced Dame in the playoffs he dropped 36.5/8/7 on his head while Klay was shooting 38/34% from the field and KD was out in a sweep. These two are not comparable and never have been.
The second series you're referencing in 2016 is when Curry came back and stabilized them against Portland. The Blazers started hitting their stride in game three and likely won the series if Steph hadn't returned.
Long as GS doesn't have a rash of injuries again this year, I absolutely expect a top four seed out of them. I agree, they have enough talent to be in the mix though without Klay, they don't have enough to beat the Lakers unless Curry is on god mode.
