2012-13: Trotman showed steady improvement in his first pro season with the Bruins' AHL affiliate in Providence before missing time due to concussion issues in the second half of the season. In 48 games he scored 2 goals with 14 assists and was +4 with 19 penalty minutes. Providence finished first in the Atlantic Division and reached the second round in the playoffs.

Trotman has gone from long-shot to long-term project. The last player taken in the 2010 NHL draft has, over the course of one season, shown marked improvement in all areas of his game, the most notable of which are his strength, skating and passing games. Originally seen as more of a defensive defenseman, Trotman opened things up a bit this year leading all Lake Superior defensemen in scoring, and was consistently up with the play and involved in the offense at Boston’s summer development camp.
Trotman will spend the 2013-14 season in Providence, but he continues to impress and is inching closer to the NHL. The Bruins have a ton of depth on defense, which could also be an obstacle in Trotman reaching the big club.
