Bob Selig or whoever needs to get tough on these peds. All Commissioners do. The right way to do it is to ban the player for the year/season, erase all of their stats, and nullify their contract. When the player comes back he and his team can write a new contract and all stats after being outed will have an asteric next to their names. Its very simple, now do it.
