It will be an awkward moment when Cousins come back, but if Dwight will give Lakers the needed boost in that position then management will have to pick Dwight then.
In Center position, I would go for Howard although he does not score much and he is not a good free throw shooter.
They need him because he can defend, and if he is still the same Howard I know, he will be a beast in rebounding and blocks in the inside, in short, he will be useful to the Lakers, yes, the Lakers needs him, hopefully this will come into reality.
Of course he doesnt play the same anymore. Age is already hitting his body.
It will not be wise if Cousins comes back in mid season and force it again to play.
I would rather sit it until a full recovery happens.
His value is getting lower and lower. He might want to come back healthy then maybe finish the season with at least 80 percent it. Somethingn like 50 to 70 games playing 10 to 15 minutes.
That wont bw bad if he can showcase his skills again.
Dwight on ths hand, he is still agile. It wont be a problem for the Lakers since AD is there. It will just low minutes for this centers. I bet they will go small when AD is on the floor.
