I think a lot of the problem is, as it's evident on this board: players blatantly go against what "stat nerds" say, because they don't feel as though "stat geeks" should have a megaphone when stating their opinions. Which is only natural; if you play a sport for a living, you're going to feel some type of way about someone else speaking about you and that sport, in general, from the confines of their couch. You're out there busting your ass against the best players in the world, and some unathletic cracka is talking about what you're doing wrong.
And then you have a flow-on from that where the NBA is a fraternity, where if one of their own is being criticized by a "stat geek", they'll feel the need to defend that player, and twist the narrative to where they'll be completely biased. Even if they truly don't believe what they're saying, or if they know what the "stat geek" is saying has some shred of truth, they won't acknowledge it. They'll just ride for their own. And that's fine, that's their right to, but nobody should be using that as evidence to suggest that Jamal's opinion holds greater value because of it.
