2010-11: Elliott made his pro hockey debut, skating in five playoff games with the AHL's Lake Erie Monsters after signing a three-year, entry-level contract with Colorado in March 2011. He had two assists and was minus-three with the Monsters.

He led the Saskatoon with a plus-62 plus/minus and scored 31 goals with 50 assists in 71 games. Saskatoon finished first in the East Division and reached the second round of the playoffs. Elliott was an even plus/minus with 3 goals and 5 assists in 10 playoff games.
2011-12: Elliott made an impressive NHL debut in November – registering points in his first three games – and was with the Avalanche through February before being returned to AHL Lake Erie to see more ice time. He was re-called by Colorado in late February and played six games before being sent back to the Monsters. In 39 NHL games with Colorado he scored 4 goals with 9 assists and was plus-two with 8 penalty minutes. He scored 5 goals with 9 assists and was plus-five with 4 penalty minutes in 30 AHL games with Lake Erie. The Monsters finished third in the North Division – missing the playoffs by two points.
2012-13: Elliott's play hit a bit of a plateau in his second pro season as he appeared in just 18 games for the Avalanche – spending most of the year with AHL affiliate Lake Erie. He attended Colorado's training camp following the NHL lockout but did not appear in a game for the Avalanche until February. Elliott scored 1 goal with 3 assists and was -3 with 2 penalty minutes; averaging 17:30 minutes of ice time. He played 44 AHL games for the Monsters and scored 5 goals with 8 assists and was -10 with 6 penalty minutes. Lake Erie finished third in the North Division but missed the AHL playoffs.
Elliott is a spectacular offensive defenseman who possesses great vision and an accurate shot. He is rarely caught out of position and comfortable at both ends of the ice, though he lacks the physical edge of the prototypical NHL defenseman.
