2010-11: McIlrath made his pro hockey debut, appearing in two games with AHL Connecticut following his WHL campaign with Moose Jaw. In two AHL contests he was scoreless and -1 with 7 PMs. In WHL play, McIlrath was once again one of the tougher defensemen for the Warriors. He was second to heavyweight Cody Beach (STL) with 153 PMs on a Moose Jaw club that finished second in the East Division. McIlrath, primarily a shut-down defender, scored 5 goals with 18 assists and was an even plus/minus in 62 games. McIlrath was scoreless and an even plus/minus in six playoff games for Moose Jaw with 15 PMs. McIlrath signed an entry-level contract with the Rangers in March, 2011.
2011-12: McIlrath returned to Moose Jaw for a fourth junior season after impressive New York Rangers coaches and staff with his play at the Traverse City rookie tournament and in the main camp. He joined Connecticut for the AHL playoffs – skating in five games and finishing minus-one with 9 penalty minutes as the Whale reached the second round. McIlrath's calling card with Moose Jaw was his physical play – though he also had 3 goals and had a career-high 20 assists. He skated in 52 games for the Warriors drawing a pair of suspensions that kept him out of eleven games and was second on Moose Jaw with 127 penalty minutes. The Warriors reached the Eastern Conference finals after winning the East Division in the regular season and in 14 playoff games McIlrath had 6 assists and was plus-three with 12 penalty minutes.
2012-13: McIlrath's rookie season with Rangers AHL affiliate Connecticut was delayed until the end of December due to a serious knee injury suffered in the summer but it took little time for him to make his presence felt. The 20-year-old unloaded a big hit on Bridgeport's Marc Cantin (which resulted in a two-game suspension) and had his first AHL fight with Sound Tigers' heavyweight Brett Gallant – both in the first period of his first game. In 45 games for the Whale he had 5 assists and was +7 and finished third on the team with 125 penalty minutes. Connecticut missed the AHL playoffs by two points despite finishing second in the Northeast Division.
McIlrath is a nasty, in your face NHL defenseman, who won’t back down and can clear the crease for his netminder. Not afraid to fight or just intimidate, McIlrath has a good shot and his puck distribution has been improving, but he needs to improve his skating and defensive positioning.
McIlrath began the 2013-14 season playing for the Hartford Wolf Pack of the AHL.
