The biggest problem with preferential treatment is on the DEFENSIVE end, not offensive. On offense, they are driving to the rim a lot, so there will be fouls (even if some are a little BS).
It's on the defensive end that stars like James and Wade are permitted to get away with a lot more contact that any other player and not get called. Wade, especially ... some of the things I have seen him get away with on defense are absurd. There is no way James or Wade would be considered as good on defense if they were actually called for all of their reach-ins and shooting fouls, instead of being gifted free steals and blocks.
