2) Bo and the media go back to an often debated question of whether or not the media has any right to be at the practices. Technically they do, and technically they don't.
Under no circumstances, either professionally or legally, does the media have any right whatsoever to be at practice.
I suppose, Nebraska being a public institution, the media could attempt to force their way in under FOIA, but even that won't get it done - likely the courts would rule that the team has a right to privacy under an amateur version of a trade secret protection (and yes I know I'm explaining that horribly, we can have a lawerly type chime in if they like).
If a court ruled that the media has rights to practice, likely the only thing they'd be able to get, after a FOIA request was submitted, would be tapes of practices from weeks, if not months prior. I can't see any legal method by which the press could force the university's hand into letting them attend live practices.
Enhance, you've mentioned that you're a J-school student. Have your instructors said anything about any possible method of gaining entrance to practice? I would be really curious to know how they'd do it.
