Nets lost their mind on this because they are chasing a championship, they forget that those three players are gonna have a hard time adjusting, they are all want to have their ball in hand, that's sometimes the issue with star players they don't want to outlast because they need attention, if the two of them won't adjust and give in to one star player I'll bet this its gonna be the worse big three ever especially Irving want to be the guy same with durant.
We will know this after 5 games those three playings together as a starter. But with Kyrie Irving's absence, I think we won't see those three playings together anytime soon. But if James Harden will change his play after him being traded to Brooklyn, this team has some potential to be a top contender in the playoffs.
If I was the Nets, I would play heavy load management to ensure that they are hardly ever on the court together. Set them 3 feet apart from each other. That way it might work out.
