Must suck when you plateau as a top 2 player in the world. I am also assuming that he has plateaued, not peaked, meaning he will be this good for a while before his game declines.
He is still over a year younger than when LeBron and MJ won their first titles. He still has the potential to get his shot figured out and get even better.
His numbers this year are off but it's only been 15-16% season so far. There is still a lot of season to go for him to be his MVP self again and see those numbers get better.
