I agree the Bronny stuff is odd, but our window is closing.   Embiid is probably on the downside at this point, his being the best player on a team might only have 2-3 years left before his leg injuries end his dominance.   Adding LeBron to him to make a run at actually going all the way seems almost necessary.   
Maxey is a good player, maybe very good, but he will never be the best player in the league.   He might be a marginal all star, certainly impressive, but he isnât going to be much more than what he is.   He will not be the best player on a Championship Team, but he might be the 2nd scoring option.  
Getting LeBron would absolutely assure us that is 2028 this team will be terrible.   But we MIGHT have a window to challenge before than.
Besides, as a Sixers Fan, I would like to see LeBron end his career here.   He is rightly one of the best players ever, and even at the end of his career still a very good player (not what he once was).   He is also extremely intelligent and capable of figuring out how to best play with Embiid.  I believe he and Nurse could solve the âhow to play with Embiidâ problem that has so far been a mystery to the league.
