Bloggers and the Media vs. Sports

For my sports journalism class, we had to read two pieces online that had to deal with sports bloggers and the media having struggles with major professional sports leagues.
In the first article, "Buzz Bissinger vs. Mark Cuban on Twitter," you see a professional blogger (Bissinger) and his one-sided argument with Dallas Mavericks' owner Mark Cuban.  Cuban started the "Twitter war" off by calling Bissinger a coward for some of the stuff that he wrote in one of his articles about player and fan stereotypes in the NBA.  Bissinger responded to Cuban with his own little rant, but when Cuban took the high road and decided to not respond back, it was Bissinger who repeatedly attacked Cuban for not backing up his claim of being a so-called coward.
Bissinger's followers got involved and also began criticizing Bissinger's pieces, in which case, he expanded his war to casual followers and attacked them for not reading his full article and reading both sides to Bissinger's claims about stereotypes in the NBA.  But, before I continue any further with Bissinger, I want to get to a second piece that ties into the media and sports issue.
In the second piece we had to read, a piece from the New York Times written in 2008, the author, Tim Arango, talks about the growing tensions between major sports leagues and media members and the restrictions being put on media outlets to only being able to publish so much multimedia content per story.  The piece starts off with a side-story about how Cuban (yes, him again) began banning all bloggers from being allowed into the team locker rooms because their credibility as journalists was lacking.  But, the NBA said he had to let major news outlet site bloggers into the team room, so his response was to let in any blogger.  Now certain leagues put restrictions on how much multimedia content news organizations can publish on a site, whether it's 30 second highlight clips, or two pictures, the leagues have control over the media.
Now, the reason I wanted to tie these two stories together before I got to my main point is because of this: a bloggers' credibility as a journalist is tarnished by what Bissinger displayed on Twitter.  There is a reason for why Cuban began banning bloggers into the team locker room and it was because he didn't see them fit to cover the stories accurately.  Now, I'm not saying Bissinger doesn't cover things accurately, but the way he acted on Twitter doesn't make him seem professional in the slightest.  He is a blogger and is opinionated, which is what differs a blogger from a regular news reporter.  But, his cursing and attacking others because they simply didn't agree with his piece shows me that he really shouldn't deserve the respect of high-ranking personnel, such as Cuban.
And it is people like him who are the reason why there are strains between leagues and the media.  Leagues are tired of unprofessional media members who abuse the power that they have to display content, so they need to decide who should cover and print what and who shouldn't be allowed to cover at all.
