They can use all their role players and let them try working together to give rest for the starters, like how GSW is doing
when they are resting their main core.
Coach Ham needs to bring his system to the entire team and not just to focus on their stars,
I agree with Davis and LeBron they are both an important part of the team and the bad effect of
them not playing, the team mostly struggle or most of the
time, they will lose the game.
They had found a system that works for them, Westbrook does not need to be a triple-double man, he can take care of the 2nd unit and they are effective with that. The Lakers now have become a threat, they were disregarded early but now they are winning games and that resulted in an improvement in their ranking.
Lakers are number 13 now but the good news is they are 7-3 on their last 10 games.
It is understandable for Lakers to push Westbrook to be a bit more alone guy. He is not leading the second unit, he is given a second unit because at the end of the day that team is not great, and he ends up playing however he wants, without looking for lebron or AD, and that means he plays better because he doesn't need to look for others.
However, when Lebron and AD plays, they all look for each other, and that creates space. This gave them a bit of breathing room and they are slightly better, still not that great though, looking at how they play they still have to play a lot better and losing games, but it does make more sense this way at least.
