Say for instance a lifetime runner never was better than 1:56 for the 800m, he's mid twenty's and decides to spare no expense with investing in every performance enhancing drug until he works his way down to 1:44.5, then he stops with the roids for 6-9 months. After having them out of his system he runs at usa's makes the world team and get sponsors, blah blah blah. What, if anything, could the usatf do about a guy like that? He cheated to get there, regardless of the fact he's clean now....
