Nate Ryan: William Byron wins wild Daytona 500, Kiwi Shane van Gisbergen debuts in Xfinity

Nate Ryan - who covers NASCAR for NBC Sports in the USA - joins Martin Devlin on It's Only Sport to talk the Daytona 500. It turned into a chaotic race at Daytona Beach with more than half of the 40-car field involved in a huge crash with just nine laps remaining. William Byron was the main beneficiary and took the chequered flag for his first ever win in the 'Great American Race'. Ryan talks to Devlin about the race including the rain delays it endured and how the wreck was caused. They also discuss Kiwi Shane van Gisbergen's debut in the Xfinity series, where he ended up finishing 12th.
