Because race alone doesn't explain this situation. Some black ex-players turned analysts like Shaquille O'Neal, Charles Barkley, and Tracy McGrady have been on record, echoing criticisms about his work ethic and labeling him a lazy player.
When pressed for evidence, they'll hide behind the eye-test claim. But just because a player doesn't spend 48 minutes diving for loose balls doesn't make him/her lazy. Admittedly, Joel Embiid's playing style can look lethargic, but it stops at that. That's his natural build and movement at 7 feet tall. It has nothing to do with the effort he is exerting.
It gets worse when you consider that the narrative has no base in reality. As I said earlier, ex-teammates and coaches speak glowingly of his work ethic.
Richaun Holmes, a current Sacramento King, and former teammate of Joel Embiid was quoted saying,
"He works so hard just to get himself in shape, get himself physically ready to step on the court. He wanted to play so badly every day that I saw him. Behind the scenes, he's such a hard worker"
"Behind the scenes, he's such a hard worker."
That's the quote for me. Just because Embiid doesn't spam social media with videos of him in the gym or post a carefully crafted picture of him getting up extra shots after a heartbreaking loss doesn't mean he is lazy or not putting in the work.
