I'm trading Lonzo while he still has value if you land Lebron/PG.
Why would they need to unless Lebron insisted on it? He'd be great alongside Lebron.
He can relieve the burden of Lebron having to bring the ball up/run the offense every time down the floor.
Because he's a pass first guy, Lebron doesn't have to worry about "touches" since Lonzo is just looking to facilitate the offense and move the ball.
