It's a huge amount of money that an NBA player would want, Davis gets the championship at get's the biggest salary in the NBA, there's no reason to leave if Indeed the Lakers will offer him that amount, he even has a bigger salary than the king.
I'm sure Lebron doesn't mind that, as long as he and Davis will be healthy in the next 4 years and bring more championship to the Lakers, he will be down with that. And AD with his first ring experience, will definitely love to stay with the Lakers. The management seems to fit the puzzle together specially when he joined and continue the tradition of Lakers winning again.
The question is will Lakers be really interested in signing Anthony Davis on his desired contract especially with the news coming in that the Salary Cap might even decrease for the next season. If this happened and Davis don't want to sacrifice money in order to win more championship I doubt the Lakers would be able to afford him. Him wanting a bigger contract and the Lakers signing them will mean that they would have less wiggle room in signing other role players to be able to make another championship team. If they want to make more championships Davis should not be looking for another max contract.
