Obviously, he can be a minority owner if he chooses. In terms of full or majority ownership, it will be tougher.
He doesn't have nearly as much shoe money coming in as MJ, so he will have to make some great business moves.
I think he can do it, but the franchise values are so high at this point, it's tough to visualize.
Yea, if Lebron wants to be the principle majority owner and keep that minimum 51%... the biggest obstacle is what Dan Gilbert's asking price would be, if or when he finally is interested in selling... in addition to any readily available multi billionaire suitors who could offer Gilbert 3-4 billion for the squad.
So at that point even if Lebron gets a team of investors to match that 3-4 billion that other potential suitors could offer Gilbert 10-15 years from now, if Lebron wants that 51% ownership... that's still a lot of cash he'd need to ensure he was still head honcho of his own investment team. Or else he'd just end up another glorified 'minority' owner / black mascot to some principle white jew owner.
It's possible, but it's definitely a bit harder compared to when Michael Jordan and Mark Cuban bought their franchises for under 300 million apiece.
