I mean, let's set aside the "possible" backdoor racism for a second (Mixtapes? Really?), and get straight to it: if Slovenian basketball was really poppin' like that, then how come the Slovenian NT is currently ranked seventh in the world? Secondly, Cuban is conflating play style with fundamentals: ball-handling is a fundamental skill. Passing is a fundamental, so is shooting, so is defense. Which of these fundamental skills are "well over 50%" of American players lacking?
Thirdly, taunting or non taunting has ****-all to do with fundamentals. That's a direct shot at the culture of American basketball and, you know what? The guy who sat around with his thumb up his ass while his employees sexually harassed women and watched porn on his dime is the last mother****er on in the entire league who should be fixing his mouth to say jack **** about basketball culture.
