NBA - Main

I’m a dinosaur and only know OG stats. I’ve sorted hated these manufactured stats but am open to change. I understand conceptually what it is (more or less) but not how it’s calculated or how it’s not sorta arbitrary. I’m not convinced it’s better especially when they say AI is overrated. Dude was a beast.

And are there other new stats I need to learn?

ELI5 but also open to complexity.
