These are exhibition games with scores of 142-141 or something like that right? Are we really going to put any stock into summer league all-star games as a way of measuring players against each other?
No which is why Durant torching the competition isn't a huge surprise. Pro basketball doesn't count unless it's up against an entire team of NBA-level players, playing NBA-quality defense, during the season where everyone is giving 110%.
Anything done against less serious competition simply isn't a true indicator.
