Rugby is a game in which the laws, although they may be written down, are open to interpretation - so writes Jonny Wilkinson in his latest column for The Times.
"We have all taken those sort of gambles over and over. When they do not come off, you are accused of having bad discipline; when they do come off, you are the hero.
"I could rewind to the weekend just past. My team, Toulon, were winning against Montpellier until the last minute, when they scored the try that stole the victory from us. What if we had gambled differently? In retrospect, if we could have, we should have. We should have spoilt, stolen or slowed down their ball to prevent their try. We should have taken the gambles that might have had us penalised but might also have allowed us to prevent that try.
"But that is how rugby works: it’s about getting as much as you can before you get penalised. That is professionalism."
