The Golden State Warriors are the meanest older brothers in the world. Most older siblings are going to beat you in whatever you're playing. They're smarter due to experience, stronger due to age, and just have more skills developed. There's always a breaking point to when the young sibling can naturally begin to catch up to their older siblings in most athletic or competitive endeavors. Until they get to that breaking point, it's up to the older siblings just how dominant they want to be.
It seems like the Warriors aren't concerned with artificially building up the confidence of their opponents, whom they treat like younger siblings.
