When Shattenkirk had a nine-game point streak for the Colorado Avalanche from Nov. 17-Dec. 4, 2010, it set him apart from almost every rookie defenseman in NHL history. Only Barry Beck had posted a longer scoring streak by a first-year defenseman (he had two 10-game streaks with the 1977-78 Colorado Rockies).

Selected by the Avalanche in the first round (No. 14) of the 2007 NHL Draft, Shattenkirk made his NHL debut Nov. 4, 2010, with Colorado against the Vancouver Canucks. Shattenkirk participated in the 2011 SuperSkills competition during NHL All-Star Weekend and finished the season with 43 points, the most among rookies. However, he didn't finish the 2010-11 season with the Avalanche.

On Feb. 19, 2011, Colorado traded Shattenkirk, Chris Stewart and a 2011 second-round draft pick to the St. Louis Blues in exchange for Erik Johnson, Jay McClement and a 2011 first-round draft pick. Shattenkirk made his debut with the Blues that day, getting an assist against the Anaheim Ducks.

In 2011-12, Shattenkirk's first full season in St. Louis, he and Alex Pietrangelo became the fourth set of defensemen in Blues history to each score 40 or more points in the same season. Shattenkirk made his Stanley Cup Playoff debut April 12, 2012, against the San Jose Sharks.

Shattenkirk reached double figures in goals for the first time in 2013-14 with 10, leading Blues defensemen. He also joined Brian Benning, MacInnis, and Pietrangelo as Blues defensemen to score five game-winning goals in a season.

Shattenkirk led the Blues with eight points in six playoff games in 2014-15. In 2015-16 he led the Blues with 20 power-play assists in the regular season, then led them with six more in the playoffs to help St. Louis reach the Western Conference Final.

Shattenkirk was named the best defenseman at the 2007 Under-18 World Championship, where he won a silver medal with the United States, and has also represented his country at the World Junior Championship, World Championship and Olympics. He won an NCAA championship in 2009 with Boston University, assisting on an overtime goal in the title game against Miami of Ohio.
