The only reason he spent any time at all at a "school" is because he had to in order to play in the NBA.
To fault him for that is silly. Fault the NCAA for this asinine system that maintains the farce of the "student athlete" at the schools with major sports programs.
Exactly.
How do we know he will show up to practice late?
Pay attention to film sessions etc.
This is a nonsensical connection to draw. In fact, if anything what we know is that he correctly prioritizes basketball over things that matter much less.
Shows you are a quitter
He doest even have to pass the classes. Just sit there like a statute. Just go.
By this definition every single NBA player who didn't get his degree could be called a "quitter."
And your proposed metric of "not quitting" is even more ridiculous. Sitting like a statue and not even passing classes will not improve either his mind or his body, and would probably do harm to both.
