At least we are having an honest discussion now but you are looking through rose colored glassed. Wasn't 2015 when he had a horrendous shooting finals?
He shot 40%, which is around what the other high usage players shot on both sides (curry or Klay may have shot 44-5). Both sides shot poorly.
He was 36/13/9, though, which I think makes up for it.
Remember they were playing without KL and KI in the finals. He still took them to 6.
