Selected by the Philadelphia Flyers in the sixth round (No. 161) in the 2007 NHL Draft, Maroon did not break into the NHL quickly, despite being a high-scoring forward in junior hockey.

He had a 40-goal, 95-point season with St. Louis of the North American Hockey League in 2006-07 and followed that with 35 goals and 90 points for London of the Ontario Hockey League in 2007-08.

But Maroon spent much of the next five seasons with the American Hockey League affiliates of the Flyers and Anaheim Ducks, who acquired him in a trade on Nov. 21, 2010, and had 32 goals and 74 points for Syracuse in 2011-12. He played 15 NHL games with Anaheim during the 2011-12 and 2012-13 seasons before becoming a regular in 2013-14, when he had 11 goals and 29 points in 62 games.

The 6-foot-3, 230-pound power forward began as a fourth-line wing with the Ducks, but his work with Ryan Getzlaf and Corey Perry in the 2015 Stanley Cup Playoffs drew notice around the NHL. His ability to use his big body effectively along the boards and in the tough areas helped open up space for his linemates to create scoring chances.

Maroon had seven goals and 11 points in the 2015 postseason, but was traded to the Edmonton Oilers on Feb. 29, 2016.

The Oilers saw his size and physicality as qualities they could use, but Maroon also gave them offense right away. In his 16 games with Edmonton the rest of the season, he had eight goals and 14 points, then had a career year in 2016-17 with 42 points (27 goals, 15 assists) to help the Oilers qualify for the Stanley Cup Playoffs for the first time since 2006. He had eight points (three goals, five assists) in 13 postseason games.

Maroon had 30 points (14 goals, 16 assists) in 57 games for the Oilers in 2017-18 before being traded to the New Jersey Devils on Feb. 26, 2018.
