There's a lot wrong with this article tbh. Good effort, but I don't agree that this is a good article.
Green didn't get a lot more wide open opportunities. Sure he had higher percentage of them, but his volume went down immensely. In 14-15, in 81 games, Green was able to get off 457 attempts. Last year, in 79 games, he was able to get off 349 attempts. The opportunities were significantly lower, and a BIG reason why is because of the lack of an effective roller in the PNR that used to create so many looks for the weakside in rhythm three. I've talked about this ad nauseam and none of the people who write about the Spurs on twitter have brought it up. I've probably brought it up in 5 different threads over the summer.
Also, he's wrong when he says Gasol's pick and pop will create more looks for Green from three. Just look how David Wests' pick and pop action last year hurt the effective ball movement when the ball was forcefully swung to the weakside for contested/guarded 3's.
