Yeah, here's the way I see the roles for the team:
Stars: Leonard, Aldridge, Gasol -- is defined mainly by the fact that they are supposed to make everyone around them better rather than specializing in one thing.
Penetrators/facilitators: Parker, Manu, Simmons, Murray
Shooters: Green, Mills, Bertans, Forbes
Roll-men/Rebounders: Dedmon, Lee, Anthony
Defenders/Macrocephaly: Anderson
If you look at the salary/production of those positions and compare them, it's obvious where the problem is. Attacking one group for not being able to do what the other group is supposed to do is silly.
