The PAC-12 network literally put this graphic out recently. Jesus...
Lebron hasn't directly said Bronny is "one and done", and that perspective probably has changed since the recent heart condition, however he definitely did say Bronny can play for the Lakers right now. I know he's Lebron, but still imagine being a Lakers or USC teammate for them. That's got to annoy some folks.
Truth be told, I see Bronny similar to LiAngelo Ball. He'll get his chances due to fame but I don't see him materializing much of a career in the NBA. I could be dead wrong of course, but most of the projections on him just seem like hype. Plus add the recent medical issues which might affect his long term outlook.
