9. The Kearneys
Rugby is one of the toughest sports on the planet but the Kearney brothers are very good at it. The Ireland internationals have achieved remarkable success at the highest level of the game. Both men play for Leinster, with whom they’ve won European Cups. Dave also played in every single game of Ireland’s 2014 Six Nations win.

However, elder brother Rob is definitely the more famous of the two. Rightfully so, as he’s been a mainstay for club and country for over 10 years. The Ireland star has won the Lions Series, four Heinekin Cups and four Six Nations. That’s why he’s one of the best fullbacks in the Northern Hemisphere.
