A lot of emphasis on N'Diaye's offense.
What you should really be talking about is his defensive rebounding and defensive versatility. Can guard the 1-5, although he can struggle in the paint with physicality. Had a DRB% of around 20%. He's especially good at using his length and mobility to secure 3pt misses of the opposing team. Something we struggled with last season.
He's as good as a defender as Mo D, possibly better, and he's 6ft 11, the same as Jelavic. This guy's defense and his rebounding, especially the rebounding, are a great upgrade on last year's 4's
He's also a way better offensive player than Dioubate, and Mo D had some solid moments on that end. This guy will be more consistent. Better handles than both those guys as well.
If he plays for us like he did in Italy, we are getting a fantastic player.
