2006-07: Maroon dominated the NAHL this season, leading the circuit with 95 points (40 goals, 55 assists) in just 57 games for his hometown St. Louis Bandits. He added an additional 23 points (10 goals, 13 assists) in 12 playoff games, en route to leading the team to the Robertson Cup championship.
2007-08: Maroon made his Phantoms (AHL) debut on Apr. 13 vs. Albany. He joined the Phantoms after concluding his season with the London Knights of the OHL, where he posted 90 points on 35 goals and 55 assists. He singed a three-year entry-level contract with the Flyers on Nov. 1. He won OHL Rookie for the Month honors for the month of October after recording 10 goals and 10 assists in 11 games during the month.
2010-11: Maroon got off to a fast start and was leading Philadelphia's AHL affiliate Adirondack in scoring before being exiled from the team at the end of October and eventually traded to the Ducks. Maroon, after scoring 5 goals with 3 assists in nine games with the Phantoms, would emerge as the second-leading scorer for the Ducks' AHL affiliate Syracuse; scoring 21 goals with 27 assists in 57 games. Maroon had 13 power play goals and the team's third-best plus/minus (+6) though the Crunch failed to reach the AHL playoffs. Maroon was re-signed by Anaheim as a restricted free agent to a one-year, two-way contract in July 2011.
2011-12: Maroon made his NHL debut in his fourth pro season – skating in two games with the Ducks – and led Anaheim AHL affiliate Syracuse in both points and penalty minutes. Maroon appeared in two October games with Anaheim before being demoted to Syracuse and was scoreless with 2 penalty minutes; averaging 12:32 of ice time. He scored 32 goals with 42 assists in 75 games for the Crunch and was plus-17 with 120 penalty minutes. In the four game playoff series with Saint John's he had no points and was minus-four with 4 penalty minutes. Maroon signed a one-year contract extension with the Ducks in June 2012.
Maroon has improved his conditioning and become a force at the AHL level. A big man with respectable mitts, Maroon has become a bankable option to win puck battles and then continue working for position down low. Solid redirecting the puck or shooting from between the circles, Maroon combines size and skill in a way that fewer players in the AHL have this season.
A power forward prospect whose development curve seems to have shifted from steep to average, Maroon should have plenty of opportunities to reach the NHL. Once he does, he could be a top-nine forward who earns some power play time for his ability to go to the net-front as well as his aptitude recovering pucks.
