Maple Leafs in the 2014 NHL Winter Classic against the Detroit Red Wings. Boston Bruins On February 29, 2016, Liles was traded to the Boston Bruins in exchange for Anthony Camara, a 2016 third-round pick and a 2017 fifth-round pick. On July 1, 2016, he re-signed a one-year deal, worth $2 million with the Bruins. In his second season with the Bruins in 2016-17, restricted by injury and also reassigned to a depth role, Liles appeared in just 36 games with the Bruins totalling 5 assists. Retirement Due to a concussion in his final year with Boston, Liles opted to end his 14-year professional career, returning to Colorado with his family and accepting a part-time role as a studio analyst for Altitude Sports in covering the Colorado Avalanche. International play Initially, Liles was selected to play for Team USA in the 2000 World Junior Championships in Umeå, Sweden, but suffered an injured shoulder in the last minute of the last exhibition game to rule him out of the tournament. During the 2004–05 NHL lockout, Liles made his international debut when he was recalled prior to his European stint with the DEL's Islerhohn Roosters as an injury replacement for Hal Gill for the 2004 World Cup. After scoring in his first exhibition game against Russia, Liles played in two games during the World Cup. Liles' place was retained within Team USA when he was named, alongside future teammate Jordan Leopold, as a part of the young core of the squad to appear at the 2005 World Championships. Liles, however, went pointless in seven games before the U.S. finished in sixth place after elimination in the quarter-finals to the tournament's eventual gold medalists, the Czech Republic. During the 2005–06 season, Liles was named to Team USA for the 2006 Winter Olympics in Turin, Italy. He appeared in all six games for the underwhelming U.S. team, recording two assists before suffering elimination in a quarter-final loss to Finland, 4–3. Three years later, Liles returned to Team USA when he was added to the team's roster for the 2009 World Championships following Colorado's cellar-dwelling season in 2008–09. He finished the tournament with the most points on the team, as well as second-most overall amongst tournament defenseman, scoring nine points from nine games. Team USA ended up fourth overall, losing the bronze medal game to Sweden. Personal life Liles married fiancée Erin Johnson in 2013.
