He proved he wasn't the:
1. Athlete
2. Ball handler
3. 3 pt shooting
4. Passer that was advertised.
He lived off of bully ball, which he doesn't have as much upside with in the NBA given his height. He also raised questions about being genetically obese by posting a body fat % of 9.8. Not a bad player, but clearly of a different caliber than the projected top 4. Has tweener status and questionable upside. Wingspan of 7"0 is decent, but his height is crap. Doesn't have handles, passing, or lateral speed to play SF.
It would be a lot easier to teach Aaron Gordon how to shoot than to teach Randle d. Adequate D, based on his combination of position, athleticism, and measurements will be next to impossible.
