2006-07: In his first year of professional hockey, Cumiskey joined up with the Albany River Rats (AHL). In 63 games, he netted seven goals and 33 points. He also got his first look at the NHL, racking up a pair of points (1g+1a) in nine games with Colorado.
2007-08: Cumiskey dressed in 38 games for Colorado, racking up five points, all of which were assists. Opening the year with AHL Lake Erie, he was recalled by Colorado on Oct. 13 and reassigned that same day. He recorded two points in five games with Lake Erie, and was recalled for a second time on Oct. 22 and spent the rest of the season in the NHL. He played in 16 straight games from Nov. 28 to Dec. 29, but was sidelined due to a groin injury, missing 17 games from Jan. 12 to Feb. 18. Jan. 30 (retro to Jan. 9) Cumiskey was placed on Injured Reserved. He was activated on Feb. 20, but did not dress during the Stanley Cup Playoffs.
2008-09: Cumiskey netted five goals and 17 points in 28 games with the Lake Erie Monsters (AHL), his second season with the club; he received an AHL All-Star Game nod for his efforts. He saw more NHL action this season, but failed to register any points in the six games he spent with the Ava’s. A shoulder injury sidelined him for most of the season.
Cumiskey is a tad on the short side, at 5'11. He is a very poised and gifted offensive defenseman, as indicated by his 40 points while playing in all 72 Rockets games this season. He is extremely versatile and can be used in all situations. He is a balanced skater with decent acceleration and overall speed. He has good hands and on-ice vision, which ultimately gives him the upper hand on the rush.
Cumiskey was dealt to the Anaheim Ducks in October, 2011.
