I guess you could say the Waugh brothers weren't to shabby but other than that here in australia I can't think of anyone else off the top of my head either mate to be honest. I am pushing a bit here but there were 2 NFL players in America who are brothers one has only recently retired Shannon Sharpe and the other who had an what looked to be an amazing career cut short after he broke vertebrae in his neck forcing him to retire I have a feeling they could have been twins actually could be wrong but they were both exceptional football players.
