I have no issue with the pre-KD Warriors. They built their team the right way and got a few breaks along the way(Barnes turning down a 65M extension, Curry signing a below market value deal).
The KD signing was one of those things that's like a solar eclipse. It was a weird quirk in the CBA that even allowed them to have the room to sign KD in the first place. It's why I don't understand why people say other teams need to get better when they literally can't do what the Warriors did. That was a one-off situation and kudos to them for taking advantage, but it's left every other team severely handicapped.
