GLASGOW, Scotland -- Anti-doping leaders were challenged to produce more credible evidence of Russian cheating by a leading Olympic executive on Saturday.Leaving a meeting of the World Anti-Doping Agency executive committee, IOC representative Gian Franco Kasper dismissed the credibility of the report that detailed Russian state-sponsored doping.Manipulation of samples at the 2014 Sochi Winter Games and cover-ups of positive tests across dozens of summer and winter Olympic sports was reported by WADA investigator Richard McLaren in July ahead of the Rio de Janeiro Games.I want to see the proof, Kasper, who is also president of the skiing federation, said in Glasgow. We cannot say its correct or not. He has to bring proof with names.Former Russian anti-doping lab director Grigory Rodchenkov told McLaren that samples of Russian athletes were passed through a concealed hole in the wall during the middle of the night at the Sochi Games, with the help of intelligence officers from the FSB, the current version of the Soviet Unions KGB.You know this hole in the wall in Sochi was Hollywood for me ... they had a key for the door, Kasper said. The KGB are so stupid they have to drill a hole in the wall? Come on.U.S. Anti-Doping Agency chairman Edwin Moses, the gold medal-winning and world record-setting hurdler from the 1970s and `80s, said it was ridiculous for Kasper to question the investigation.Wave after wave of retests show that there are Russian athletes (doping), Moses said after attending the WADA meeting with Kasper.You can go back one or two Olympic Games and it just seems like wave after wave of Russians are showing up (as having doped) which really cuts through the credibility of the results of those Olympic Games and the redistribution of medals. To me thats a horrible situation.The latest batch of retests of samples from the 2008 Beijing Olympics saw the IOC announce on Thursday that four Russian athletes, including three medalists, tested positive for banned substances.The credibility of Olympic medals has diminished and thats what the athletes are believing, Moses said. You have scores of athletes out there who should have won medals and now know they were right.That is why Moses, like WADA, wanted the entire Russian delegation banned from the Rio Games in August, a move that provoked the ire of the International Olympic Committee.The IOC rebuffed those calls, instead allowing individual sports to rule on the eligibility of Russians.Three months after the Rio Games, the rifts remerged in public at an Olympic gathering this week in Qatar, where the IOC questioned Craig Reedies WADA leadership, demanding a neutral president. Reedie is still set to be re-elected unchallenged for a second three-year term at the WADA Foundation Board meeting in his native Scotland.There is no point at the moment walking away from this situation when things need to get done and things get difficult, Reedie said on Saturday. There are people demanding improvements in process and I want to get that finished as well.A WADA Foundation Board meeting on Sunday will see a discussion of the WADA leaderships push for enhanced whistleblowing mechanisms, and bid to codify a sliding scale of sanctioning powers, including fines or blanket bans on entire countries or sports for the type of widespread doping scheme it believes was run by the Russian state.WADA only tried it once with the Russians in Rio and the IOC said no -- its none of their business, Kasper said. It has to be a neutral institution and it shouldnt be political. ... You cannot be the prosecutor and the judge yourself. Its the basic principle of justice.---Rob Harris is at www.twitter.com/RobHarris and www.facebook.com/RobHarrisReportsMaury Wills Jersey .

He journeys between Vegas and Los Angeles in a fleet of cars worthy of his surroundings. His cryptic retirement and the cancellation of his next bout caused shock but, when tracing his swift rise to the pinnacle of the fight game, perhaps we should have seen it coming.Business is never personal but it can be cruel and ruthless, McGregor told Sky Sports in 2014 after just three UFC wins in an eerie foreshadowing of his own fate. The businessman in the dickie bow and cufflinks found a roaring trade in the fight game but he always insisted his fists were money-makers - he became the first athlete in his sport to pocket a seven-figure windfall in his last outing and could now eye different investments of his time. McGregor pulled from UFC 200 UFC confirm Diaz rematch is off after cryptic tweet When a guy like me comes along with the number of people that I bring with me, everyone else has to step aside Conor McGregor in 2015 Little over a year ago, before he beat Dennis Siver, McGregor told Sky Sports: When a guy like me comes along with the number of people that I bring with me, everyone else has to step aside. I feel like a veteran now. I have found comfort in this circus. I find comfort in the uncomfortable. My goal is to be the best version of myself that is possible - and the best version is the greatest fighter of all time. That is my goal.By retiring at the pomp of his abilities and fame McGregor will have established himself as the ringleader of the circus that employs him. Cutting that chord altogether is the act of either a brave or a foolish man - but McGregor signalled an intention to play by his own rules long ago. Conor McGregor lost in March to Nate Diaz and has been withdrawn from a rematch The Crumlin Boxing Club, where he first laced gloves as a novice, remember a youngster never afraid to make shocking decisions. Phil Sutcliffe, the first man to teach a 12-year-old McGregor to punch, still hasnt digested the news that his pupil chose to immerse himself in the dirty secret of MMA.Some kids had more talent than Conor but didnt work as hard, Sutcliffe told us. He was like any other novice who we taught the basics to - hands up, chin down, elbows in. When he got good enough he was able to drop his hands because he could read the punches. When he got good enough, he took his shoes off and learned to grapple - a seemingly bizarre abandonment not dissimilar to his UFC retirement. McGregor also had a negative reaction to his first loss, explained Owen Roddy (right) I remember the first day meeting him, said Straight Blast MMA gyms Owen Roddy. I remember the confidence Conor had. He was immediately the best boxer we had. You could take him down and submit him but he was never fazed. He knew he could knock you out. But it wasnt plain sailing, even in those days, after a bad reaction to his first pro MMA defeat in his third fight.He went missing for a while, Roddy told Sky Sports. It was in Crumlin and there was a lot of support for him. He gave up training for nearly a year. Eight years ago, the broke McGregor was coaxed back - but will a sweaty gym be as attractive this time?A second loss in his sixth fight triggered a different reaction. From then on, he was open to every aspect of the game, Roddy said. Anywhere he felt lacking, he focused all his time there. Instead of shying away he threw himself in at the deep end. Like the Crumlin Boxing Clubs trainer, head coach Kavanagh emphasises McGregors normality: He isnt talented or gifted. Nobody is born knowing how to play the guitar. He isnt talented or gifted. Nobody is born knowing how to play the guitar. McGregors coach John Kavanagh He had a modest 4-2 record in 2010 but, in two years, reeled off eight consecutive finishes while his larger-than-life personality came to the fore. One of those victims, Dave Hill, told Sky Sports: I thought it was all an act, all for show. He was kicking off at the weigh-ins. But whhen he got in my face, because of his intensity, I thought he really believes in himself.dddddddddddd. That flustered me.Yet the Rolls-Royce that he currently drives was still a pipe dream. Thousands of miles from the riches of the UFC, McGregor was still collecting benefits until April 2013 when he got his call-up. Coach Kavanagh told us: It was my first time as a coach at that level so it was new to all of us. Before he knocked out Marcus Brimage, he walked over to me and said this feels no different to the gym. The $60,000 bonus after his 67-second KO was celebrated wildly yet three years later would be loose change in the back pocket of his newest suit. McGregor (left) knocked out Diego Brandao in Dublin It took a year to shoot from the undercard to the main-event in Dublin against Diego Brandao. McGregors evolution incorporated a snarling gorilla tattooed onto his chest and his reputation was just as fearsome. Brandao fell inside one round but McGregors quotes to Sky Sports hinted at a man keen on sporting legacy rather than financial gain.The more I look into my family history and the McGregor name, it was bred on battle, he said. It makes me realise that this chose me, I wasnt meant to do anything else. Im going to change the way martial arts is viewed. Im going to change the game. Im going to change the way people approach fighting. Success is never final, Ill just keep on going. McGregor (left) beat Dustin Poirier in Las Vegas As the paydays grew, did his attitude change? A Las Vegas debut against Dustin Poirier was his toughest test so far but the defeated American later told us: Ive had 19 fights and Ive never been put out like that, Conor is definitely the real deal. McGregor, reflecting on that knockout, revealed his incentive.He told Sky Sports: When Dustin fell I thought of the money. I have a good 20 seconds of thinking about a nice, fat cheque before I think about the next one. I didnt celebrate because its a done deal. Its over and done with in my mind, I know whats going to happen, and I consistently tell people exactly how it will happen. Then I go out and execute it. I celebrate as soon as the contract is signed. Eighteen months and multiple contracts down the line, is his retirement talk really a surprise?Before his world title challenge, the UFC insisted he travel to Brazil to sit at ringside for Jose Aldos defence against Chad Mendes. Far from a jolly on the Copacabana, McGregor outlined to Sky Sports the purpose of the journey. Everything I do is big, big business. The option was there to go on [UFC chairman Lorenzo Fertittas] private jet but in my mind, I only want to travel on my own private jet. Conor McGregor in 2014 This is business and pleasure. Im going to enjoy it because I dont have to compete but everything I do is big, big business. The option was there to go on [UFC chairman Lorenzo Fertittas] private jet but in my mind, I only want to travel on my own private jet.Now the featherweight champion and beneficiary of the sports largest ever purse for a fight, jetting about on McGregor Airways is realistic. Those who call him a friend insist he still preaches the same virtues, albeit from behind the darkened window of a £300,000 Roller. Aisling Daly, a UFC fighter who shares his gym, told us: Hes still the same guy that I knew when we were teenagers but he has fancier shoes and nicer cars. Everything else about him is the same. Sometimes Conor will turn up for training in a five-piece suit but, on a normal day, hes rolled out of bed and arrived in a beanie hat and a tracksuit.If this wild ride is over, it will end with some unfulfilled prophecies - he once told Sky Sports a sold-out Croke Park fight was a done deal, its one contract signature away. Outside of the cage those contract signatures have become McGregors expertise but, if he returns, his next fight will be around the negotiating table. McGregor & Rousey: What now?
