What about if they trade for Anthony Davis
In January, Anthony Davis requested a trade with hopes of landing with the Lakers. However, the Pelicans refused to blink and elected against trading Davis to the Lakers, or any other team ahead of the NBA Trade Deadline for that matter.
If this offseason the Lakers can convince the Pelicans to trade them Anthony Davis, they can have two elite players in LeBron and AD. But with all of this, if you can convince Horford to sign for less than the max contract you should sign him.
He can be a solid contributor who can play off the ball with LeBron running the offense and Davis carrying the scoring. He can help defend the top big man of rival teams and let Davis rest a bit on the defensive side of the ball. Davis and Horford would fit nicely next to each other.
