Early in his men's career Plys was twice invited to be alternate on Shuster's team at international events, at the World Championship in 2009 and the 2010 Winter Olympics. At the Olympics he was called in to skip the team (in place of Shuster) during draw 6 after the US team suffered four losses in a row, and led the team to a 4–3 victory over France after a 10th end steal. Following the Olympics, Plys was drafted onto Tyler George's team, where he threw third rocks (and sometimes fourth). The George team finished as runners-up in the 2011 and 2013 national championships. In 2014, Plys moved to third on Heath McCormick's team, which placed third in the 2014 and 2015 national championships, and second in both the 2017 Olympic Trials (to Shuster) and 2018 national championships.
