Regarding the Marion debate, he was a fantastic defender in his younger days and an amazing rebounder. But if Kevin Durant is a black hole then I don't know what is worse than that but Marion was it. He is and has always been one of the worst ball stopping players around and a too be polite, not the best passer either.
He had chemistry issues when he was younger because of his ego and thinking he should get even more shots than he got.
So I see both sides of that article and from my own recollections of him and those times. Freakish athlete and fantastic basketball player. Great defender but he had his warts as well. As every player does.
