the biggest difference between the public and analytics models on rating nba players is the public tends to value players more for 1v1 skills rather than 5v5 skills. In 1v1, you either have the ball or are guarding the ball. In 5v5, you are offball a lot on both ends, spacing, passing, rotating, reading passing lanes, boxing out and rebounding, and dealing with a much more cluttered and complicated game. it's a different set of skills. nevertheless, the eyetest tends to focus on the 1v1 skills in the 5v5 game, because that's where the ball is. of course, the 1v1 skills are very important in the 5v5 game, but there's another group of skills that shift the evaluation. so in JB's case, i think he's a top 15 1v1 player in the league, but ranks lower in 5v5, because he's not as strong in the 5v5 skills.
