Can Žižić play and be a good NBA player? I say yes he can and will be. Why? Because he has the proper height for an NBA center, he is a tough as they come, has a good motor, and most importantly he is a high character guy and a hard worker. He is not afraid of contact, not afraid of competition, humble guy, and got his brother's guidance. Believe me, he will be a better player then Nurkic...
I definitely agree that he will be better than Nurkic.
I never saw Nurkić getting anything but backup center minutes in the longterm.
He has a Bosnian head (may sound racist, but even Bosnians make jokes about it, basically means stuborn), 400 lbs potential (see his dad), in love with his car (during his Cedevita stint guys close to the club were telling me that it is worrisome), discipline, injury risks...
On the other hand, Žižić is younger, really experienced for his age (played 3 leagues simultaneously just 2 years ago, now in Turkey), has that grown man's counter-strength, a kind of Steven Adams immovable object trait. Big thing for a - big. He can control the defensive glass, a must-have skill for a lone big in today's game. Slow release, but good accuracy from the midrange and FTs. Great motor. He will never misinterpret his skillset to overthink his role, unlike Nurk, who is skilled but not that skilled to be jacking some questionable shots or going for a home run play that has only 30% of succeeding. Žižić doesn't get frustrated, he just plays. I think that Nurkić is back in Europe in some 3-4 years.
But the fundamental drawback of this Nurkić addition possibility is that at the moment we don't want to add any more guaranteed salaries after this year.
We would all rather have Hayward than Nurk.
