You don't think it was humiliating for KD when Draymond told him "We don't need you. We won without you." for all the world to witness? Some would argue it's even more so.
I don't think it's any different, and I don't think it's anything this squad can't overcome. They've been through worse times.
Many thought the Warriors couldn't get past that, and they did, where only injuries stopped them from winning that season. Whatever happens this season, the Warriors' championship hopes are not going to be decided by this. I said earlier in the thread, but in 1-2 months time, this will be forgotten, and there'll be some other fukkery that occupies our minds.
The fact this happened before the season even begun should give even more credence to them working towards moving past this, and it being a distant memory by the time the postseason rolls around.
