I said Harden is very good and efficient, but he's probably not worth the max. My thought was based on the observation during last year's playoffs. He was the best closer and efficient player for them in 2nd half. However, I believed that he got that many FTs, partially because OKC did get some favorable calls, because of their style of playing. If he goes to some other team, he won't be able to continue.
But I was wrong, he's been flourishing since day one. Sometimes he just seems to be effortless to score at will. It was a steal for Rockets.
