Scotland cannot blame referee, says coach Scott Johnson Interim head coach Scott Johnson refused to join in the criticism of referee Craig Joubert following Scotland's 28-18 loss to Wales. The home side grew increasingly annoyed by the South African official's handling of a scrappy match. But Johnson said: "I am frustrated but I have said in the dressing room we have to acknowledge our ills. It is easy to criticise one man, but we have to look at ourselves and understand what we are doing wrong. Scotland's points came courtesy of six penalties from scrum-half Greig Laidlaw, in a game dominated by the whistle of Joubert. "We showed great heart and great resolve but we have to look at ourselves rather than at anyone else," continued Johnson. I don't want to coach a side that apportions blame to someone else, we will go back and have a look and if we have to make changes we will do so, but we will go to Paris next weekend to compete.
