Lakers were missing both AD and Lebron, and they still won. Not that it means Lebron and AD are bad for this team, but the fact that they managed to beat Celtics with this squad is an insane achievement. The only reason for their success was the fact that they played big team ball and that is always good.
When you have stars, everyone else gets cold and then they look like they are missing a lot of shots, but when you shoot once every 7 minutes, it's normal that you would get cold and when you have stars then that happens because stars shoot the ball most and then you get the ball in rotation with everyone else and that turns out to be very few times. They need to start sharing the ball a lot more early on, to get people going at the start of the game, then Lebron or AD could take over if they have to.
