The thing about sports reporting is that all the major outlets have contracts with MLB, the NFL and the NBA. As such, reporting that damages the game is discouraged, as it potentially could damage ratings. So, they'll tee off on individuals, but they're not going to report on anything that could damage the game.
When Tim Donaghy got caught betting on NBA games he was officiating, the sports press IMMEDIATELY jumped on the NBA line that it was one rogue referee. What passed for investigative reporting was reading NBA press releases. Same thing with the steroid thing in baseball. You won't see the sports press get dragged into this at all if they can help it, and kicking and screaming and covering for MLB if they're forced to cover it.
BTW, my big prediction for the upcoming year: Big money sports takes a huge dive. Disposable income is down, and a lot of people aren't going to have money for $15 parking, $75 tickets and $8 beer. I think the team that takes the biggest hit is the Dallas Cowboys. They're opening a 1.3 billion dollar stadium, and Wade Phillips will bring them in at around .500.
Very good points.
