"FILE - In this Nov. 19, 2010 file photo Sebastian Coe, then Chair of the London 2012 Organizing Committee at the IOC Coordination Commission pauses during the closing press conference in London at the close of a three-day visit by IOC officials checking on preparations for the 2012 Olympic games in London. Entrusted with cleaning up a sport mired in sleaze and doping deceptions has proved far trickier for Coe than the pursuit of gold on the track. It's a year since Coe's misguided pronouncement that Lamine Diack, his predecessor as president of the International Association of Athletics Federation, was the ""spiritual leader"" of athletics.
