The Olympics haven't even begun and the military is already being called. This time, however, North Korea has nothing to do with it. Almost a thousand military personnel have been sent to Pyeongchang after dozens of security guards fell ill from a norovirus outbreak. Nick Dimengo, Senior Editor at FHM Magazine, joins with a preview of the top athletes to watch. Lindsey Vonn makes her return to the Olympics in South Korea after missing the 2014 Winter Games due to injury. Dimengo says Vonn has a strong chance of medalling after winning her last two competitions leading into the Olympics. Veterans like Vonn aren't the only names to watch going into Pyeongchang. Dimengo says he has his eyes on three big breakout stars from the U.S. Olympic Trials. Ice skater Nathan Chen, snowboarder Chloe Kim, and speedskater Maame Biney are all at the top of their game despite being teenagers.
