I mentioned this to the guy who sits next to me, and he couldn't think of another game where this was a case either. In the whole 80 minutes, not only were all the points scored by try or conversion, there were no kicks from either side that even attempted a kick at posts from a penalty. In every case, the teams went for the line-out/corner option. I can't recall a game where the only attempted kicks for the posts were conversion attempts. Can anyone else think of any other examples in the last 10 years? I'm struggling to find any other case...
