I still really like Hezonja and think he's more gifted than Hayward.
How's his jumper coming along?
His jumper is fine. I believe he will have no problem regarding is shooting. He might only have consistency issues for a while on the higher levels he is currently playing in and in the future.
More gifted than Hayward? I don't know, it's arguable. Athleticism wise, definitely. Game wise, they are too different players to compare but I'd take Hayward without thinking much. Hayward is just much more versatile player and that makes him very valuable in my opinion. Yes, Hezonja has a very exciting game, he is like, (regarding his upside) a more explosive version of Ginobili but his passing game hasn't shown the improvement I hoped, his help defense is still bad and I have big question marks about his character. Good thing, he has a Kobe-like work ethic. But the bad thing, he has the worst Diva attributes as well. It will make him either a star in the future or a disappointing non-fulfilled potential.
If you'd say Saric, however, him being a ridiculously talented big man, plus surprisingly maturing very well, I'd go with Saric.
Isn't Hezonja known as a ball hog in Europe?
More like disoriented. Yes, he was also a ball hog in the teams that have been made around him in the past, but he was always way above his competition level not to be. Still, I think his team play is a serious issue at this point. Probably his biggest weakness. But there is just no way currently for him to be a ball hog in his current level, he's being tamed hard these days in Euroleague and the ACB, I hope it will help him about it.
