Everyone has a job to do. If you're in PR, you have a responsibility to the team to make the team look good. That's what they hire you to do. The team is the one who's paying the PR guy, not the newspapers.
As for reporters/bloggers, they can write whatever they want within the laws of libel and the standards of their paper (in the case of reporters).
If the PR guy for the Wings doesn't work well with some reporters/bloggers who don't report the team in a good light, he's just doing his job. It doesn't silence the reporters/bloggers. It just means that they don't have a red carpet that leads straight to their information.
There's news and there's opinion. If a reporter is reporting news (i.e. Wings sign Player X) then what will be reported is the facts. If the reporter is posting opinion (i.e. Player X is the next big thing) then that is what will be published.
The PR people have a responsibility to provide the news reporters with their facts. Any opinion reporters can take those facts and comment at will, but it's the PR guy's job to see that the news reporters get accurate data.
As a hyper-fan, I'd love to get more inside information, but these guys are people with lives and it's also the PR guy's job to protect that whilst still giving fans access to the players. If you work for the team, you're not going to work with a reporter/blogger who wants access so he can rip a player apart or throw him under the bus. That's not taking care of your team, which is part of your job. There has to be a level of trust there if we expect the players to open up to the media for us.
I'm checking the news daily in hopes of seeing "Danny DeKeyser re-signed" and when I do, I will first seek out the facts, and then come here to get all of the opinion I can handle on the subject. Sure, I will probably read some opinion articles and some blogs if I run into them, but at the end of the day, any one of us here who is reasonably literate could be a blogger if we really wanted to.
