With most of those guys, it's the defense. LeBron went from a really good two-way player to a sieve defensively. Durant isn't there yet, but I don't see the explosive ability to cover the whole court that he showed in his prime. And Jokic, I thought would be Kanter-level bad defensively, and that hasn't been the case. He's actually been really good. But in terms of footspeed, he just is what he is, and it's not going to get better. I know the advanced metrics love his defense, but then I see what Golden State is doing to him defensively, and it makes me really question the value of his defense, especially in the playoffs.
Agreed on Curry. It's so hard to measure how the way he changes what defenses want to, and the way his gravity warps the floor, impacts an offense, even when his shot isn't falling.
