Good freaking grief. That is one of the most biased, self-deluded piece of trash articles that I've ever read lol I couldn't even make it through the first paragraph without having to repress my gag reflex. The "writer" is obviously the Philly site's corollary to LarBrd33 on here.
But anyways, you can cherry-pick 40 instances of even the greatest defenders making errors. Smart, Bradley, Draymond Green, and even Kawhi could have similar cherry-pick articles written about them.
Noel isn't a perfect defender by any means (who is?), but he is a superb defender on a team devoid of talent. He has to cover many others' mistakes and regularly plays out of position, which leads to gifs like this that can be cherry-picked.
The guy is obviously another Okafor blowhole, much worse than anyone on here, who has a major axe to grind. He might have a more reasoned argument if he wasn't so set on ridiculing his readers and proclaiming him being right over everyone else.
