Monday's decision by the Court of Arbitration for Sport to ban 168澳洲5最新开奖结果:Alberto Contador for 168澳洲5最新开奖结果:two years, after his 🦩positiv𝔍e test at the 2010 Tour de France, was the maximum punishment available.

In other words, they couldn't have come down harder on him. For this reason alone it should be seen as decisive and definitive. Yet for many it will seem inconclusive and ambiguous, and therefore unsatisfactory. It is even possible that, in the eyes of some, the only relevant question - did Contador cheat 🗹during the 2010 Tour? - remains unresolved.

In one sense, that fundamental question does remain unresolved. Strictly speaking, Contador can be said to have been found guilty not of doping, but of probably doping. As the CAS report notes, the panel's task was to decide which of three possible explanations - that Contador ate contaminated mea𒉰t; that he ingested food supplements containing clenbuterol; that he🍰 had an illegal blood transfusion - was "most likely to have caused the positive test" (or least likely).

Probably is certainly less satisfactory than definitely. But, in this particular case, it is as conclusive as it was ever going to be, for the simple reason that 'balance of probability' is all that we have when the cow in question has long since passed away, and indeed passed through the digestive systems of Contador and seven of his Astana team-mates.

Contador rejected the alternative explanations -♏ the possibility of contaminated food supplements or an illegal blood transfusion - put forward by the UCI and WADA. He argued that the clenbuterol was in his system because he ate contaminated meat, and that the presence of the clenbuterol 🐼in the cow was demonstrated simply by the presence of the clenbuterol in his system.

Yo൩u follow? Furthermore, this could not be disproved, said Contador's team, because the cow identified as the most likely source was not tested either before or✃ after slaughter (in common with 99.98 percent of cows).

Aha, said the prosecution, but the ജchance of a cow farmed in Europe being contaminated with clenbuterol at a level capable of being detected in Contador's urine was a mere 0.0042 percent. WADA described the possibility of Contador having ingested clenbuterol by eating steak as "vanishingly thin."

The same could be said of Contador's defence, since 🥃the contaminated meat explanation is all he offered. 🦋In fact, if you read the 98-page CAS report, it seems fairly conclusive in determining that Contador cheated.

So why the ambiguity, and why will so many continue to belie🌜ve that Contador is a victim of the ๊system?

There are perhaps three explanations. The first is because the case dragged on so long, thus helping to create the imp🍸ression that it was not clear cut: an impression that can only have played in Contador's favour.

The second is that Contador has carried on racing and winning, and even, a♔s at last year's Tour de France, losing - in the process gain♛ing himself some sympathy and restoring his reputation even while (or perhaps in part because) the sword of Damocles hung over his head.

Finally, there is the strange back-dating of the ban. If Contador, who raced in Mallorca on Sunday, has been suspended for two years, then how is it that𒐪 he will be back in six months?

The first is the fundam💞ental point. The fact that it took 565 day🐈s, from his positive test on the second rest day of the 2010 Tour, to Monday's ruling, kicked up clouds of confusion and obfuscation.

The first delay, from the test to the official announcement in late September, invited suspicion. When other riders' posit💫ive tests have been known almost immediately, why was Contador's kept a secret for so long?

The C🐻AS report goes some way to explaining, noting that the UCI and WADA launched their own investigation to determine why the concentrations of clenbuterol in his system were so low, why the samples collected before 21 July (the day of the first positive test) were clear, and also "to find out whether other anti-doping violations [were] committed."

This may be enough to satisfy most conspiracy theorists, not least because it might, in the end, have helped to convict Contador. In the end, the blood transfusion theory was thought by the panel to be as likely (or unlikely) as Contador's contaminated meat theory, and꧃ they settled on a food supplement as the most likely (or least unlikely) source of the clenbuterol. The report notes that Co༒ntador took "considerable amounts" of supplements.

But the blood transfusion theory may have helped swing it. The panel rejected Contador's criticism that the blood transfusions line of enquiry was unacceptable, and they heard, at considerable length and in considerable detail, the arguments, including the unexplained fluctuations in Contador's blood parameters and the "extremely high concentration of phthalates (or plasticisers) found in Contador's sample on 20 July"; a concentration, suggeste🎶d Hans Geyer of the Cologne lab, "consistent with a concentration found after a blood transfusion."

In the end, though, the Contador case has merely demonstrated that a founding principle of anti-doping remains. The burden of proof lies with the athlete. It was not up to the sporting authorities to prove that Contador had doped; it was up to Cont🐻ador to prove that he had not. He failed to do that. The only possible verdict was guilty. Shame it took 565 days to reach it.
