After a weekend of 6 nations rugby, English Premier League and Scottish Cup football, I asked myself 'how long would a professional footballer last in a game of rugby?' The footallers go to ground and wriggle about after the slighest knock, while the rugby players get up after 35+stone of flesh and bone take them clean off their feet. I would guess the footballers wouls last no more than 5 minutes (as long as no one ruined their hair 1st).
