I'm leaning number three.
Although, if Lebron wants to win one more championship, coming to Phoenix is not so far fetched. LA is hiring a new coach to develop the younger talent on LA. Phoenix is a 30-40 minutes private jet flight to LA. CP3 proved you could be with family and play in LA. Lebron said he's not interested in playing back east. The only other place I could see him doing this vet minimum move if he leaves the Lakers, is the Clippers.
It's funny, all of a sudden we get on getting a G League team, to develop younger talent, and Bronny comes up as a possible draft pick? It's also funny how the fan base here in PHX isn't jumping on the Lebron train. Probably from the KD experience.
