Major League Baseball doesn't rewrite history, so there's no changing the fact that Milwaukee outfielder Ryan Braun is the 2011 National League Most Valuable Player and not Matt Kemp. However, Braun's trophy might be getting a little less gleamy.Braun is currently challenging a positive test for a performance-enhancing drug, report Mark Fainaru-Wada and T.J. Quinn of ESPN.com.If the finding is upheld, Braun won't have to give back his trophy, but he will have to give away 50 games of the 2012 baseball season to a suspension.
