The media has to pick their battles. Sure, Butch has some pretty strict rules concerning what media is allowed to report on from practice, but under Dooley the media was seeing a lot less of practice to begin with.
FWIW I think there are plenty of sports media in Knoxville who do a good job in their reporting. Dustin Dopirak is professional and brings reliable information. Wes Rucker is admittedly a total douchebag, but when it comes to actually giving write ups and practice reports he does a decent enough job. Jimmy Hyams never really breaks any headlines, but he's a cautious reporter who calls things pretty fairly when it comes to the university.
The VQ guys have a great relationship with the athletic department and coaches (to the extent that some have called them little more than mouthpieces for the AD), but that usually means that the info they bring is solid.
I honestly don't think the Knoxville sports media is quite as terrible as many have made it out to be. And I don't see any problem with the coaches prohibiting media from reporting on any specifics concerning injuries or personnel they see during practice.
