More than 200 teams from across the world traveled to Memphis for what USA Today calls the best barbecue challenge in the nation. Big Bob Gibson, led by Chris Lilly, previously won in 2000, 2003 and 2011. The team also took the top prize for best pork shoulder over finalists Red Hot Smokers out of Olive Branch, Miss., and Boarhouse Smokers out of Bartlett, Tenn.
