Fwiw, Johnson did what he did and got an edge from it. That English side were never going to lose that day after 01 but Johnson saw that Ireland were a young side led be a green captain in BOD and took advantage. I doubt he'd have tried the same if Wood or Galway were captain as they'd have gotten their team to stand up face to face with the English and told them where to go.
Johnson did however disrespect Irish rugby, our president and, if they're your sort of thing, the values of the game by doing something that he knew was wrong. So, just like Jones when he was out of line commenting on Johnny Sexton's health, you as an English fan don't have to think any less of what he did but he was in the wrong and is seen as a knobend the rest of the world over for a reason!
The ROG pic has been more than cleared up at this stage... It's just a funny, opportunistic pic now.
