by Jim Davis - Over the Christmas period, mobiles were lighting up with Tweets about USA rugby player, Carlin Isles. The message was simple, "Look at the speed of this guy." WATCH THE VIDEO. The 23yr old is a former track and field college star who ranked as the 36th fastest man in the USA before embarking on his rugby career and has a PB for the 100 metres of 10.13. Yes, a twitch over ten seconds. That time would have been good enough to qualify for the semi-finals at the London Olympics last year. Bryan Habana is fast right? Isles is in another league and likely the fastest man to take to a rugby field. And to further blow you away...at the time of the recording he had been playing rugby for just on 3 months. With 6 tries so far in the current IRB World Sevens Series and this video going viral with over 2 million hits, Isles is now on the radar
