John Carlson (born January 10, 1990) is an American professional ice hockey player who is a defenseman for the Tampa Bay Lightning of the National Hockey League (NHL). He was drafted by the Washington Capitals in the first round, 27th overall, in the 2008 NHL entry draft after playing a year in the United States Hockey League (USHL) with the Indiana Ice. He has also played for the Anaheim Ducks. Before reaching the NHL, Carlson played junior hockey in the Ontario Hockey League (OHL) with the London Knights and played professionally with the Capitals' American Hockey League (AHL) affiliate, the Hershey Bears. He also participated internationally for the United States in the 2010 World Juniors and 2014 Winter Olympics. Carlson won the Stanley Cup as a member of the Capitals in 2018, as the highest-scoring defenseman during the playoffs.
Carlson was born in Natick, Massachusetts, on January 10, 1990, to parents Richard Carlson and Angela Dalle-Molle. Carlson is of Swedish descent on his father's side. The family of four lived in Marlborough, Massachusetts, where Carlson learned to skate, until his father accepted a job in New Jersey when John was around five years old.
After his family moved to the Colonia section of Woodbridge Township, New Jersey, Carlson and his brother Andrew played junior hockey for the New Jersey Rockets in the Atlantic Youth Hockey League. In his freshman year at St. Joseph High School, Carlson played for both the varsity team and the Rockets in the 2004–05 season. He recalled being one of a few players who joined the Rockets Junior A team at the age of 15. Carlson played all 21 games for St. Joseph, registering 12 goals and 19 points, to help lead the team to the New Jersey State Interscholastic Athletic Association Sweet 16 tournament. However, this would be his only season playing for St. Joseph as he then dedicated his sophomore and junior years to the Rockets. While playing for the Rockets under coach Bob Thornton during the 2006–07 season, Carlson scored 50 points in 44 games to earn the Atlantic Junior Hockey League Offensive Defenseman of the Year Award. Throughout his time with the Rockets organization, Carlson gained the attention of scouts for the National Hockey League (NHL) and United States Hockey League (USHL). He was also recruited by Hockey Hall of Fame defenseman Bobby Orr to become his client.
The attention eventually resulted in him transferring to Cathedral High School in Indianapolis for his senior year to play one season with the Indiana Ice in the USHL. As a 17-year-old, Carlson played 59 games with the Ice, recording 12 goals and 43 points. He was subsequently named to the USHL's 2007–08 Second All-Star Team and All-Rookie Team. Before the start of the 2007–08 season, Carlson committed to play college hockey for the University of Massachusetts Amherst and expressed his excitement to join the team. However, after he was drafted by the London Knights in the 2008 Ontario Hockey League (OHL) draft, Carlson chose them over the NCAA. Before the 2008 NHL entry draft, Carlson signed an Ontario Hockey League (OHL) contract with the Knights. Leading up to the draft, Carlson was ranked 17th among North American skaters by the NHL Central Scouting Bureau and was expected to be drafted in the first round. He was eventually drafted in the first round, 27th overall, by the Washington Capitals.
Following the NHL draft, Carlson participated in the Washington Capitals training camp and played in two preseason games before joining the Knights for the 2008–09 season. After scoring four goals and 10 assists over his first 12 games, Carlson signed an entry-level contract with the Capitals on November 13. Carlson's defensive play helped the Knights hold a 9–1–0–0 record through December and he began the 2009 calendar year ranked third among all rookies in scoring. As a result, Carlson was named the OHL Rookie of the Month for December. Carlson also led all OHL defencemen in scoring through January and was recognized as the OHL's Defenceman of the Month. During the month, he scored points in nine games and maintained a five-game scoring streak. He was also selected to participate in the 2009 OHL All-Star Classic. He finished the regular season with 16 goals and 60 assists through 59 games and added another 22 points over 14 playoffs games. He was recognized by the Knights at the end of the season with various honors, which included the Booster Club player of the year, play-off performer of the year, best defenseman, rookie of the year, and most valuable player. The OHL also selected him for the OHL Second All-Star Team, OHL First All-Rookie Team, and the CHL All-Rookie team.
Washington Capitals (2009–2026)
Early years and development (2009–2013)
After the Knights were eliminated from the playoffs, the Capitals reassigned Carlson to their American Hockey League (AHL) affiliate, the Hershey Bears, for the 2009 Calder Cup playoffs run. He made his professional debut in Game 1 of the division finals against the Wilkes-Barre/Scranton Penguins and scored his first professional goal in Game 2. Carlson finished the playoffs with three points over 16 games en route to the Hershey Bears' 10th Calder Cup championship title.
Carlson stood out to the Capitals coaching staff while attending their development camp ahead of the 2009–10 season. Capitals head coach Bruce Boudreau described him as "easily" the most NHL-ready out of all the prospects in attendance. Carlson was reassigned to the Bears to start the 2009–10 season. He scored his first AHL regular season goal on October 17, 2009, against the Binghamton Senators. He tallied four assists in the next few games and finished the month leading all Hershey defensemen in scoring. He was called up to the NHL level on November 18 and given the jersey number 74. He made his NHL debut two nights later, on November 20, 2009, against the Montreal Canadiens. At the age of 19, Carlson became the youngest player to make his debut with the Capitals since Alexander Semin in 2003–04. He played 17:24 minutes in his debut and recorded one shot on net. Carlson remained in the NHL for two more games before being returned to the Bears. Upon returning to the AHL, Carlson was selected for the AHL All-Star Games and was loaned to United States junior team for the 2010 World Junior Championships. Following the tournament, Carlson alternated between the two teams before finally staying with the Capitals from March until the end of the season. He finished the 2009–10 AHL season ranking fourth among all rookie defensemen with four goals and 35 assists through 48 games. As such, he was selected for the 2010 AHL All-Rookie team. While he did not finish the regular season with the Bears, Carlson was honored as their Rookie of the Year and best defenseman.
Carlson scored his first career NHL goal against the Carolina Hurricanes on March 25, 2010. Despite losing 3–2, Carlson tied an NHL record by being one of three rookie defensemen to score a goal that game. He finished the regular season with six points through 22 games and remained eligible for rookie status the following season. While both the Bears and Capitals qualified for the playoffs, Carlson remained at the NHL level for the entirety of their conference quarterfinals series against the Canadiens. As a 20-year-old rookie, Carlson played in all seven games and ranked third among Capitals defensemen in ice time. He scored his first NHL playoff point, an assist, in Game 1, and tallied his first playoff goal in Game 2. His goal forced the game to overtime where teammate Nicklas Bäckström secured the win for the Capitals. Carlson finished the playoffs with one goal and three assists as the Canadiens eliminated the Capitals in seven games, squandering a 3–1 series lead in the process. Following their elimination, he rejoined the Bears for their second-round series against the Albany River Rats. Carlson recorded one assist and six shots on net in Game 4 to help the Bears advance to the AHL's conference finals. However, he struggled throughout the series, and tallied only one assist over six games as the Bears advanced to the 2010 Calder Cup Finals. Carlson tallied his first goal of the AHL postseason in Game 4 of the Calder Cup Finals against the Texas Stars to even the series 2–2. His second goal came in Game 6 to help lead the Bears to back-to-back Calder Cup championships.
