Belleville missed the OHL playoffs; finishing fourth in the East Division. Not among the 210 North American skaters in the Central Scouting final rankings, Marchment was selected by Los Angeles in the sixth round (157th overall) of the 2014 NHL Draft.
2014-15: Marchment attended his first NHL training camp with Los Angeles before being returned to Belleville for his second OHL season. He skated in 22 games for the Bulls — receiving a 15-game suspension along with Peterborough’s Greg Petzold for a social media incident in November — and he and Bulls’ leading scorer Remi Elie (Dallas) were acquired by Erie in a trade with the Bulls in January 2015. Marchment scored 10 goals with 13 assists and was +14 with 42 penalty minutes in 51 regular season games with the two teams. Erie finished first in the Midwest Division and reached the OHL Finals against Memorial Cup champion Oshawa. Marchment scored 8 goals with 6 assists and was +3 with 4 penalty minutes in 19 playoff games.
2015-16: Marchment attended his second training camp with the Kings before returning to Erie as a 20-year-old. With Connor McDavid no longer around the Otters were expected to fall back into the pack but that was not the case. Marchment scored 25 goals with 20 assists and was +14 with 60 penalty minutes in 60 regular season games, scoring nine of his 25 goals on the Otters’ power play. Erie finished first in the West Division and advanced to the Western Conference finals, falling to Memorial Cup champion London. Marchment scored 4 goals with 7 assists and was -1 with 2 penalty minutes in 13 playoff games. Marchment was not signed to a contract by the Kings, becoming an unrestricted free agent.
Marchment is the nephew of long-time NHL defenseman Bryan Marchment. Taken by the Kings' with a late-round flier in his second year of eligibility in the 2014 NHL Draft, he has the size and awareness to be a solid two-way center. He is not overly-skilled in terms of scoring or playmaking ability but skates well and uses his size to force turnovers along the boards and in the forecheck. Marchment plays a solid game in his own end.
Marchment skated for the OHL's Erie Otters in an overage season in 2015-16. He was not signed to an entry-level contract by the Kings, becoming an unrestricted free agent. Marchment will need to address his skating skills to have a shot at playing in the NHL but his willingness to do all of the hard jobs, his strength in tight spaces, and his hockey intellect suggest he can be a lower line center.
