Carlin Isles might have started the HSBC Sevens World Series as a virtual unknown - but quick as a flash the American has become a worldwide hit.
Given his blistering turn of pace, it is perhaps unsurprising that Isles had also attracted the attention of the NFL clubs. However it was rugby that caught his eye - and Isles is confident he has the pace to overcome his lack of size. "The NFL scouts they loved me because I had a 4.1 second 40m and that drew a lot of attention," Isles said. "I never thought I was too small, I always believed in myself. Anything that I choose I have to prove myself. "One thing you can't teach is speed and everyone is looking for speed. I could play so I wasn't worried about my size because I have heart. But I decided to do track and go professional and pursue that instead."
