What Is The Fallout Over Ryan Braun?

ESPN:

National League MVP Ryan Braun, who last season led the Milwaukee Brewers to their first division title in nearly three decades, has tested positive for a performance-enhancing drug and faces a 50-game suspension if the initial finding is upheld, two sources familiar with the case told "Outside the Lines."
Major League Baseball has not announced the positive test because Braun is disputing the result through arbitration.
A spokesman for Braun confirmed the positive test Saturday and issued a statement: "There are highly unusual circumstances surrounding this case which will support Ryan's complete innocence and demonstrate there was absolutely no intentional violation of the program. While Ryan has impeccable character and no previous history, unfortunately, because of the process we have to maintain confidentiality and are not able to discuss it any further, but we are confident he will ultimately be exonerated."
USA Today reported Saturday night that Braun said of the test result: "It's B.S."
The 28-year-old Braun had to provide a urine sample for testing during the playoffs, and he was notified of the positive test sometime in late October -- about a month before he was named the National League's most valuable player.

Man, that defense sounds a lot like something Floyd Landis might have said.  This is just brutal for baseball.  One of their fresh faces, who just won the NL MVP, tests positive for steroids, just slightly after they start to gain some credibility that the testing program has prevented stars from cheating (not including Manny Ramirez, who's job is to be the target of hate).  For Braun, it delegitimizes his entire season, which was a career year.  It opens up the old wounds over player performance, and who's juicing and who's not.  How often do the players face testing?  How random is the program?  Can guys easily game the system?  Is anybody clean?  This sucks all of the oxygen out of the room in the Hot Stove League.  Baseball is back under the microscope, and steroid questions will overshadow every accomplishment on the field in 2012.
