I'm not completly buying the story that no MLB superstars have tested positive after Raffy Palmeiro.
MLB could have swept the positive results of superstars under the rug. Can MLB be depended upon to police themselves, considering the history of looking the other way on the steroid issue? Perhaps they decided MLB could not withstand another revelation bigger than Raffy.
So under this scenerio, a way was found to find grounds to let the players "win" their appeals, and this would explain all the rumors too.
The names could be forthcoming next week or next month. Look how long the Raffy appeals took.
Bottom line, this type of discussion is healthy. I look back with sadness upon the days of naive fans applauding McGwire's breaking the HR record, of Giambi hitting two monsterous HR's off Pedro Martinez in game seven of the ALCS to get the Yankees into the 2003 World Series (Giambi was juiced), of Barry Bonds making every pitcher look like a slow pitch softball pitcher (Bonds was juiced).
No more naivity. Let the free discussions on who may be on steroids continue until there is a foolproof, trustworthy method that guarantees that none of these guys are. And that means a testing regime, imposed by Congress, which includes at least one random blood test per year.
