Twenty seconds into the second period of Larkin's NHL debut for the Detroit Red Wings against the Toronto Maple Leafs on Oct. 9, 2015, the center from Waterford, Michigan took a pass from Henrik Zetterberg and shot top shelf past goalie Jonathan Bernier. Larkin also added an assist in the 4-0 victory.
Selected in the first round (No. 15) of the 2014 NHL Draft, Larkin became the first teenager (19 years old) to play opening night since Mike Sillinger in 1990-91. He made the NHL after one season at the University of Michigan, where his 47 points (15 goals, 32 assists) led Big Ten rookies and placed him second in the NCAA among freshmen. Foregoing his final three years of college eligibility and signing a three-year entry-level contract, Larkin began his pro career with Grand Rapids in time for the American Hockey League playoffs, where he scored three goals and five points in six games.
