2012-13: Miller was the fourth-leading scorer amongst OHL defensemen; playing for Sault Ste. Marie as an overage 20-year-old in his third season. He scored 20 goals with 35 assists and was +13 with 78 penalty minutes. Eight of his 20 goals came on the power play. The Greyhounds reached the OHL playoffs after finishing second in the West Division. Miller was -1 and scored 1 goal with 6 assists in the six-game series with Owen Sound. He signed a three-year entry-level contract with the Kings in July, 2013.
2013-14: Miller skated in 65 games for Los Angeles AHL affiliate Manchester in his first pro season. He scored 5 goals with 12 assists and was +5 with 35 penalty minutes. The Monarchs finished first in the Atlantic Division but were defeated by Norfolk in four games in a best-of-five first round playoff series. Miller played in three of four playoff games and was -2 with no points and 6 penalty minutes.
2014-15: Miller spent his second season with Kings’ AHL affiliate Manchester and was among the league’s biggest surprises. After steadily working his way into the lineup as a rookie, he was the team’s third-leading scorer, and top offensive defenseman, while also playing with an edge. Miller scored 19 goals with 22 assists and was +11 with 82 penalty minutes in 70 regular season games. The Monarchs finished XX in the XX Division, and XXX to XXX in the Calder Cup Finals. Miller scored 2 goals with 8 assists and was +12 with 12 penalty minutes in 19 playoff games. In June 2015 he was one of the players acquired by the Bruins from Los Angeles as part of the Milan Lucic trade.
Miller was drafted as a long-term project when the Kings selected him as a 19-year old in his second year of draft eligibility in 2012. The progress he has made since then is noteworthy. A bit undersized but with some elements of offense and pugnaciousness at the time, he spent an overage season in the OHL and has come into his own as a prospect in his second AHL season with the Manchester Monarchs. He has natural leadership ability and is among the team leaders in points and penalty minutes. Positionally, his defensive game is still erratic at times but his lapses have become less common and he is playing in more situations for the Monarchs.
Long-term Miller must continue to address his defensive game and work to add the strength and agility necessary to compete in the NHL. His progress to this point suggests he can be an effective lower pairing defenseman — with the ability to contribute on the power play — at that level in the future.
