Not a big fan of Mayweather's constant antics but I do applaud him on calling out Shane Mosley on his EPO use. I never understand why he and Roy Jones get a free pass with their history of using performance enhancing drugs. In no way do I condone the unforgiveable act Margarito committed (I think he should have done time in prison and have been banished from the sport) but isn't using enhancers which allow you to train harder, which in turn allows you to be stronger faster or better conditioned then otherwise possible a threat to the health of the man across the ring from you. Now obviously it's to a much lesser degree then what Maragarito did but I still feel they get too much of a pass from the public for the serious offence they comitted
