media bias in sport

What are the implications of media bias in sport? Consider what types of topics you believe to be appropriate to report on versus what you believe should be off-limits.
Do you believe it is fair for media commentators to speak about athletes in regard to their race, ethnicity, or national identity, rather than by how they are competing during international competition? How do you address this?
What type of information should (and should not) be reported in the media? For example, should the off-the-field (or out-of-the-arena) behavior of an athlete be detailed in the media?
