He will eventually become like LeBron who will have a huge influence inside the management.
I think it's too early for that for his career to bring a demand like that, he has not proven anything yet, like carrying his team to the finals, like what LeBron did in 07, until he realized he's not getting any help from the Cavs management.
The Mavs are in a better spot right now. Luka just need to make his teammates getting involved more offensively.
Here's to hoping that Luka won't end up demanding a lot from the management and getting all the attention get up to his head. He's still getting better each time, and we haven't seen prime Luka Doncic yet. Hopefully the Mavs management take advantage of their current position while Luca is still happy with the current setup and build the team around him with better teammates that has the offensive power and can make plays for him as well. The man also needs to be more active in terms of leadership in order to have his team motivated to play instead of just relying on himself to win games for the team.
Not sure if he is happy or not, he is still very young and probably not demanding any at this point. But there will be a time that he might ask Cuban to surround him with better role players, who can really help and contribute not just playing just for the sake of being in the team.
He already shows that he can carry the team, but it's not always that he will have to do that because his body can only take so much in the grueling 82 games and then we have the playoff.
He probably is demanding a star player like him, like what Lebron, Durant, and Curry have at the moment. Luka alone will make him predictable, and I'm pretty sure he will just always try in the playoffs but he will not be even be in the WCF.
