My explanation in this article about why I gave KD an 8. Just to be clear, I gave him a 10 before the injury. It's all about predicting performance not the past.
Sunny Saini, ESPN Stats & Info (rated Durant 8 of 10): "I gave Durant an 8 because of the potential of missing more than 6 to 8 weeks. Plus, he'll need to get in game shape and his minutes will be monitored for most of the season and rightfully so. OKC is better off developing Perry Jones and Jeremy Lamb while KD slowly finds his rhythm. He looked exhausted during the playoffs last season, so having a healthy, rested and more dangerous KD should be the plan."
