Andrews left University of Virginia in 2012, his junior year, and signed a professional contract with Adidas through 2017. In 2013, he joined the New York New Jersey Track Club and coach Frank Gagliano while keeping Adidas sponsorship. However, after a period of time he decided to leave the New York New Jersey Track Club, favoring a return to his UVA coach Jason Vigilante. He qualified at the 2016 Olympic Trials by kicking into the second qualifying position. Later that year he participated in the 2016 Olympic Games where he was disqualified in the semi-final round for stepping inside of the curb while executing his kick. In the 1500 meters final at the 2017 USA Outdoor Track and Field Championships, he outkicked Olympic gold medalist Matthew Centrowitz Jr. to take first place with a time of 3:43.29, capturing his first-ever national championship.
