Usually hockey players must hit the ice to make history. Not so for Johnson.

When the St. Louis Blues selected him with the No. 1 pick in the 2006 NHL Draft, the Bloomington, Minn., native became the first American-born defenseman chosen first directly from USA Hockey's National Team Development Program. He was also the second United States-born defenseman to be the top pick, following Bryan Berard in 1995.

A mobile skater with a big shot and a 6-foot-4, 230-pound frame, Johnson made his mark as soon as he joined the Blues following one season with the University of Minnesota.

The 19-year-old rookie assisted on a Keith Tkachuk goal for his first NHL point in the 2007-08 season opener. In his second game, Johnson scored on the power play for his first NHL goal as the Blues beat the Los Angeles Kings 5-3.

Johnson led all Blues defensemen in scoring with 33 points that season and finished 12th in voting for the Calder Trophy, awarded to the NHL's top rookie.

A golf cart accident sidelined Johnson for all of 2008-09 with torn knee ligaments, but he returned to form in 2009-10, leading St. Louis defensemen in goals (10), assists (29), points (39), shots (186) and power-play goals (6).

The Colorado Avalanche acquired Johnson as part of a four-player trade on Feb. 19, 2011. He scored his first goal with the Avalanche against the Blues in his second game with his new team, helping Colorado to a 4-3 win that snapped a 10-game losing streak. Johnson finished the season averaging 24:33 of ice time per game while scoring three goals and 10 points.

Johnson made his Stanley Cup Playoff debut April 17, 2014 in Colorado's first-round series with the Minnesota Wild. He led the Avalanche with 30:22 of ice time and assisted on the game-tying goal in what would be a 5-4 overtime win in Game 1, and added his first playoff goal as the Avalanche lost Game 7.

Johnson earned his first All-Star Game selection in 2014-15, though he did not play because of a knee injury that sidelined him for the final 34 games of the season. Before the 2015-16 season, Colorado signed Johnson to a seven-year contract extension through the 2022-23 season.
