They need to help him and not letting him do everything for the team, that's the problem last season they let LeBron handle the ball for almost the entire games, his teammates lacks of participations bring additional burden, if Lakers wanted the best from LeBron they need to back him up in all aspects, though chemistry really hard to blend but dedications might lift the entire team.
If we are talking about the young players of Lakers here, I hope so that someone from them will be confident to showcase their true skills while playing alongside with LeBron with no pressure and intimidation at all. LeBron needs that kind of teammates.
If talking about the veterans, with the attitude of Rondo and Stephenson I think they will not become a Cavaliers 2.0 teammates wherein they will rely mostly on LeBron in terms of playmaking, ball movement, attacking the paint etc.
I think these young players are excited since chances of playoffs appearance is now within their reached. Not just them but the whole Lakers nation. Their last playoffs appearance was way back 2012-2013 season.
