He was the third player taken in the 2011 USHL Futures Draft (by Dubuque) and was selected by the Sarnia Sting in the eighth round (155th overall) of the OHL Priority Draft. Downing committed to playing college hockey at the University of Michigan in 2013-14.
2011-12: Downing played for the USA Under-17 Select team at the 2011 Five Nations Tournament in August before joining older brother Jake Downing with the USHL's Dubuque Fighting Saints. One of the youngest players on a team that featured NHL first round picks Zemgus Girgensons (BUF) and Michael Matheson (FLA) he scored 4 goals with 10 assists and was minus-one with 68 penalty minutes. Dubuque finished third in the Eastern Division and reached the second round in the playoffs. Downing scored 1 goal with 1 assist and was minus-three with 4 penalty minutes in five playoff games.

2012-13: Downing returned to Dubuque for his second season and represented the USA in a pair of tournaments — serving as a team captain for the U18 team at the 2012 Ivan Hlinka Memorial Tournament in August and winning a silver medal at the 2012 U19 World Junior A Challenge. He also played in the 2012 CCM/USA Hockey All-American Prospects Game in Buffalo in September. Downing was plus-16 with 3 goals with 20 assists in 52 games and was second on the Fighting Saints with 107 penalty minutes. Dubuque finished first in the Eastern Conference and defeated Fargo in the finals to capture the Clark Cup. Downing had 3 assists and was plus-six in 11 playoff games. In four games at the WJAC he had 1 assist and 28 penalty minutes. Downing was ranked 49th amongst North American skaters in Central Scouting's final rankings prior to the 2013 NHL Draft.
Downing has good size but could stand to fill out his frame a bit. He is an excellent skater and isn't afraid to carry the puck up the ice, but he has yet to fully display true offensive ability. Downing also has to develop a better feel for the game, and he could stand to be a more physical defender in his own end.
Downing will play for the Michigan Wolverines in the fall. He projects as an eventual bottom-pair defender with offensive upside, but will almost certainly play his full four years of NCAA eligibility before entering the professional leagues.
