Complete crap analysis.
Dude is 6'4" with 6'10" wingspan, natural above average NBA athleticism and a very, very solid work ethic.
There is zero chance he's a bad defender. Playing for us he has the chance to become a great defender.
He's 18 years old and has never had to play defense in his life because he's such a prodigical scoring machine.
Collge has shown him the importance of good D seeing his team getting beat even with his amazing scoring.
Anyway , watch some interviews of this guy.
He's like a less hood upbringing version of Marcus Smart.
He wants to be great.
He understands the high pick and roll better than most average NBA players, he'll soon understand how important defense is and he'll bust his ass to be a great defender.
