2005-06: Brett Bellemore saw limited ice time in 46 games with Plymouth in the OHL. Had no points with 16 PIM and was -8 for the year. Also appeared in ten playoff games and was -1.
2006-07: Bellemore led the OHL in plus/minus (+48) and was named the Plymouth’s Most Improved Player for the OHL champion Whalers. Bellemore notched 12 assists in 50 games. In 20 OHL playoff games, he had 5 assists and was +12 with 28 PIM. He added one assist with 4 PIM in the Whalers' five Memorial Cup games.
2007-08: Bellemore doubled his point output in his third full season in Plymouth, scoring his first six OHL goals, three of which came on the power play, to go with 18 assists in 56 games. He also had two assists with 8 PIM and was -2 if four OHL four playoff games. Made his pro debut following the OHL season, appearing in in four regular season and five playoff games with Albany (AHL) with no points, 12 PIM and was +1.
2008-09: Started the season in Albany but after seeing limited ice time and then suffering a back injury was reassigned to Plymouth as an overager. Bellemore was scoreless and -3 in his six-game stint with the River Rats but seemed to get his back on track with the Whalers, being named the OHL's top defensive defenseman in one coaches' poll. In 29 regular season games with the Whalers, he scored 2 goals with 10 assists and was +22 with 39 PIM and had 1 goal with 2 assists in 11 playoff games with 6 PIM and an even plus/minus.
2009-10: Bellemore was again assigned to Albany after attending Hurricanes camp and had a much better season, proving to be the steady, reliable defensive defenseman he was in juniors. In 75 games with the River Rats, he scored 1 goal with 6 assists and was -5 with 81 PIM. In the playoffs, he and the rest of the River Rats faltered in the second round series against eventual Calder Cup champion Hershey after defeating Scranton-Wilkes Barre in four straight games. In 8 playoff games, Bellemore had 1 assist with 2 PIM and was -6.
2010–11: Bellemore provided a solid, stay-at-home presence and some physical play for Charlotte in his second full AHL season. In 71 games with the Checkers he scored two goals with 8 assists and was +8 with 74 PMs. In the AHL playoffs, he had 1 goal, a short-handed tally, with 1 assist and was -4 with 12 PMs in 16 games. Bellemore signed a two-year, two-way contract with the Hurricanes in July 2011.
2011-12: Bellemore played a shut-down role for Carolina's AHL affiliate Charlotte in his third pro season. He played in 76 games for the Checkers, scoring 1 goal with 9 assists, and was minus-15 with 60 penalty minutes. Charlotte finished third in the Midwest Division; one point out of an AHL playoff spot.
Bellemore is a big stay at home defenseman who is willing to drop the gloves. He seemed to develop some playmaking skills in his last two seasons of junior but has been hesitant to do that so far at the pro level. Not particularly mobile or fluid, his game is predicated on sound positioning and consistent effort.
Bellemore projects as a lower pair defenseman but is the type of player who is consistent enough to warrant pressure minutes, particularly when a team is killing penalties or playing with the lead. His lack of offense or flashiness sometimes makes it difficult to recognize his value to a team.
