Played his minor hockey career with the NASA Hockey Association, in Calgary, Alberta.
In 2007–08, Green emerged as an elite NHL defenceman while playing on a young and talented Washington team that included forwards Alexander Ovechkin, Alexander Semin, and Nicklas Bäckström. He earned the nickname “Game Over”, made popular by play-by-play announcer Joe Beninati after Green’s game winning goals in the last minutes of the third period or overtime became a regular occurrence. He finished the season with 4 game winning goals to go with his league-leading 18 goals among defencemen and 56 points. Green did not start his goal-scoring run until after Bruce Boudreau replaced Glen Hanlon as head coach on Thanksgiving Day, 2007. The Capitals made the playoffs for the first time since 2003 that season and in his first career NHL playoff game on April 11, 2008, against the Philadelphia Flyers, Green brought Washington back from a 4–2 deficit with two goals in the third period. The Capitals eventually went on to win the game on an Alexander Ovechkin game winning goal. Known for his very powerful and heavy shot, Green took a slapshot from the blue line that same game that was blocked by Philadelphia’s Patrick Thoresen. The shot broke Thoresen’s protective cup and nearly ruptured a testicle. He had to be taken to a local hospital and missed the next game. After the game, Green called Thoresen to check in on him. In game three, on April 15, Green recorded a Gordie Howe hat trick (a goal, an assist and a fight) in a 6–3 loss to the Philadelphia Flyers. The series went the distance, but the Capitals would lose in the seventh game.
During the 2008 playoffs, Green’s signature “faux hawk” hairstyle received increased publicity as his profile in the NHL was raised. An Elliot in the Morning promotion, “Rawk the Hawk,” had Green into the studio for the haircut, which willing fans could also have done for playoff tickets. The D.C. morning talk radio show has brought back this promotion for the 2009 season, offering tickets for the first game of each new series. Additionally, during the season, an unofficial Green fan club, dubbed the “Gang Green” began showing up to home games wearing dark green t-shirts with “Gang Green” written on the front and Green’s nickname, “GAME OVER”, as the name plate on the back above the number 52.
At the end of the season, on May 21, 2008, Green was named to the Sporting News‘ NHL All-Star team along with teammate Alexander Ovechkin. Later in the summer, Green signed a four-year contract extension with the Capitals, on July 1, averaging to $5.25 million a year.
Green picked up where he left off in 2008–09, but was plagued by injuries early in the season. Returning from the sidelines, Green captured back-to-back NHL Third Stars of the Week for the weeks ending February 1 and 8, 2009. On February 14, Green scored in his eighth consecutive game setting the NHL record for most consecutive games with a goal by a defenceman. The former record was set by Mike O’Connell in the 1983–84 NHL season. Then, after receiving a Second Star of the Week for the week ending March 23, he became just the eighth defenseman of all-time to score 30 goals in a season in a game against the New York Islanders on April 1. Finishing with 31 goals on the season, Green tallied 18 on the powerplay, one short of Sheldon Souray‘s 2006–07 record of 19.
Following his breakout season with the Washington Capitals, Green debuted for Team Canada at the 2008 World Championships as the host country. He recorded 12 points in 8 games as Canada went on to win a silver medal, losing to Russia in overtime of the gold medal game. Green was named to the Tournament All-Star Team.
