Dustin Johnson: Drugs, affairs with PGA Tour colleagues' wives and the silence that shames golf Firstly, the alleged womanising: Robert Lusetich, the respected Fox analyst and author of a book about Woods" fall from grace, wrote after the story broke that it was "not a huge secret that Johnson had affairs with two wives of PGA Tour players - one broke up the marriage." Secondly, and more seriously, the drug-taking: Johnson had tested positive three times since 2009, twice for cocaine and once for marijuana, and yet it was not until the real reasons were blown off his withdrawal this summer from all competition that the tour decided to divulge any of it. We can debate the merits or otherwise of being as high as a kite while standing over a slippery four-foot putt, but this is not really the point. The disgrace is that the tour knew full well what Johnson had done, but resolved to tell the world nothing beyond a clumsy, ambiguous statement that he was taking some time away to sort his life out. This is entirely in keeping with their secret-society mentality elsewhere. In China last week, the PGA Tour made clear their disapproval of Patrick Reed for calling himself a "f------ faggot" on live television after a careless three-putt, but refused to say even if they would fine him. Golf remains unforgivably opaque on matters of discipline. When the European Tour fined Woods for spitting on a Dubai green and when the PGA Tour sanctioned him last year for criticising a match referee, there was no attempt on either occasion to specify the level of punishment. Penalties are kept in-house and Johnson's drug transgressions are thus treated with nothing like the seriousness they deserve. If you needed yet another reason why golf should not be in the Olympics - and Darren Clarke was adamant this week that he would not be in Rio, arguing the Games should "represent the pinnacle of amateur, not professional sport" - it is that it displays little commitment to honouring the drug protocols required. Yes, there is far more random testing, but the Johnson case proves that there is also an unseemly scramble to conceal the evidence whenever a drug test comes back positive. If the tour will not even bother to explain his offence, then where is the harm to his reputation? Johnson is simply the sinner they would rather you did not know about. It is worth recalling this when he makes his scheduled return next February at the Pebble Beach pro-am alongside Mr Gretsky, in some horribly hokey effort at playing the scolded son-in-law. Johnson has brought golf into disrepute, and ought to pay his penance. In this episode there should be no easy absolution either for him or for the game itself. Golf had to be dragged kicking and screaming to the drug-testing table but has continued, even as a controversial member of the Olympic family, to pay mere lip service to the essential spirit of transparency. Dare to ask them about Johnson and you would get a straighter answer out of the Knights Templar. Remorse must be prerequisite for rehabiliation The spectacle of Ched Evans training again with Sheffield United is one to make any right-thinking person's skin crawl. This is not to call for extra-judicial punishment upon time already served, but simply to acknowledge the fact that one crucial element of rehabilitation is remorse - of which Evans, a convicted rapist sent down for five years, has shown none at all. His restoration also offers a dreadful indictment of football's scrambled web of morality. In a sport where narcotics, assault and drink-driving can all rightly get a player sacked, raping a woman apparently offers no barrier to reacceptance. Evans is stubbornly unrepentant because he maintains he is innocent, but that should have no bearing on this case when a jury of his peers decided differently. TV presenter Charlie Webster has, thankfully, seen sense, resigning from her position as patron of the club in despair at the boys" club of Bramall Lane. She appears to recognise that reintegrating Evans, however tentatively, sets the most appalling precedent.
