Catch me if you can – Miles Craigwell's career has taken off since he swapped NFL for rugby sevens. The 27-year-old joined the Miami Dolphins after college but failed to make the grade. It was after a chance viewing on TV that he decided rugby was the way forward.
Air Miles – Craigwell will be aiming to score more tries when the Sevens World Series arrives in Las Vegas in late January. He hopes to have friends and family watching as part of a big home support.
Jetting back – Craigwell is one of several players to swap the sports. Australia-born U.S. rugby representative Hayden Smith spent 18 months with NFL side New York Jets, making five appearances as a tight end. He returned to English rugby club Saracens in December 2013.
Scottish switch – Former Scotland rugby captain Gavin Hastings (left) won a World Bowl title with Scottish Claymores in the now-defunct NFL Europe competition, which ran from 1991-2007.
New England to new pastures – Richard Tardits made the move from NFL to rugby following three years with the New England Patriots in the early 1990s. He took part in the 1999 Rugby World Cup with the U.S. national team and also played for French club side Biarritz.
World's best – Martin Johnson, who led England to Rugby World Cup glory in 2003, has always been a huge fan of the NFL. He spent time training with the San Francisco 49ers in 2001 and has used gridiron as an inspiration for his coaching plans.
