I think you all missed the point of his original comment. He's not arguing Trae is better or has more potential. He's simply noting that he enjoys watching Trae play more than Luka. One is a diminutive dynamo, lighting it up from anywhere on the court he wants to, and creating a ton of exciting plays for both himself and others. The other pounds the ball into the sand and just tries to bully 5 other defenders (while everyone on his team watches) until there's a foul or he's scored. I will note, Trae seems to be *trying* on defense. He doesn't do a great job staying in front of his man, but he deflected/swiped at the ball multiple times after intentionally allowing a player to drive by him. When you think about it, it's kind of topsy-turvy Semi redux. One stays in front of his man but doesn't make a play on the ball, the other allows the defender by him but makes an attempt on the ball. You can call it lazy defense, but it's disrupted C's players more than once.
Luka is a better player and obviously has a higher ceiling, but Trae indisputably plays a more aesthetically pleasing and exciting (to my neutral eyes, anyway) brand of basketball, that also happens to be more relatable. Whatever you think of their skills, who would you rather play with in a game of pick up?
