The sport of rugby sevens (which, surprisingly, features seven men as opposed to fifteen) will be making its debut at the 2016 games, which could be beneficial as a stepping stone for the future addition of the full-fledged game. Popular across the globe, its hard to understand why rugby hasnt been contested at the Olympics since 1924. Back then, the game struggled to attract teams, which wouldnt be a problem nowadays, given that 80 teams are competing for 8 available places at the 2015 Rugby World Cup. Though union is truly an international game, its hard to say the same of rugby league, given that its popularity is almost exclusive to Yorkshire, Lancashire and a few Australasian countries. One day, perhaps, it might be viable candidate, but for now, union is king, and deserves a place at the worlds greatest sporting event, if only to witness the priceless sight of New Zealands All Blacks performing the haka on an Olympic podium.
