I am not a sporty person so I am very much a spectator, but as a youngster I was taught boxing, so when I watch a fight I understand exactly what is going on. There is no doubt at all that Joe Joyce won his bout by a margin and should have been awarded the gold medal. He was very gracious in his disappointment and must be commended for that. There is always the potential for controversy with judged competitions in any sport and it says much for judging quality across many disciplines that arguments are rare. In this case, and once the dust of Rio has settled, some further examination of what exactly was going on is certainly justified and I think essential. Doping is not the only threat to Olympic integrity.
