Arizona cardinals offensive lineman Kelvin Beachum is a man on a mission. Before he heads into his 12th season in the NFL - he's been using his off season to help communities in Zambia - building wells, and providing access to safe drinking water. He travelled to Lusaka, Zambia, working with the charity World Vision - as they aim to help 800 thousand people in the southern African country by 2025.
