Sports Journalism Jumping the Gun?

I am a huge sports fan and watch a lot of ESPN. A big story in the sports world lately has been the ongoing saga to get Jason Kidd traded from the New Jersey Nets to the Dallas Mavericks. The media portrayals that happened with this trade have happened lately with a lot of things in the news, especially in sports. ESPN wanted so badly to report the story first, they reported that the trade was official before it actually was. It was all over ESPN and on ESPN.com, and they were already interviewing players to get their thoughts on the trade. The reporters kept saying "their sources" were sure that the trade would get done and everything else was just a formality. Well, as it turns out, the initial trade didn't go through for a couple of different reasons. This doesn't so much bother me as the fact that ESPN doesn't seem to care when their reporting is wrong. They just came out the next day reporting that the trade hadn't gone through, without mentioning how they were wrong, leaving fans scratching their heads.

I guess my biggest problem is that there no longer seems to be accountability for these reporters. We are always taught to double- and triple-check our sources to make sure that the information we publish is correct; however, when you look at situations such as this, these people are constantly publishing things that are wrong. We are always told that the one thing a journalist needs to keep is their credibility. But are these people not still considered "experts" even after they're wrong? It just seems like in the "real world" reporting false information isn't such a big deal, as long as you come out later and correct yourself.
