If LeBron wants to win another ring, he should take a pay cut. But that would only make sense if the Warriors' management improved the bench, i.e., found some good role players. Then the Warriors, with the Curry-LeBron duo, would definitely be contenders for the title.
I highly doubt Lebron will accept a pay cut in able to fit on Warriors. I mean Curry, Jimmy and Green already occupying a lot of Warriors salary cap which means they can’t afford to get an All star caliber like Lebron.
Lebron has a lot of ring and very successful career. It’s wise for him to just stay on the team that gives him more salary while he is still active since he has only few years before he retired.
Lakers is the most perfect team for him to retired or Cavs.
