"You guys are crazy Khazzhou has been awesome. His per 36 minute numbers are top notch"
He's good at getting numbers, but he's no good at making his team better.
He plays without intensity and is arguably the worst ball-screen defender in the league, meaning teams just have to get him (and Cadee or Thornton) in pick-and-roll situations and they get good looks.
If I was building a team I'd take Jawai, Knight, Petrie, Majok, Jackson, Pledger, Ogilvy, Burston or Kay at centre over Jules. I'd also take Kickert, Johnson and Tragardh despite their defensive issues because they play harder than Khazzouh.
If your centre doesn't defend it's very very hard to win. As I said earlier, I hope he plays under a coach who lights a fire, whether that's in Sydney, another NBL club or OS, because he's a wasted talent at the moment.
