In 24 midget games he scored 3 goals with 14 assists and had 20 penalty minutes. In six games at the YOG he had 3 assists and was -6 with 8 penalty minutes in six games. The USA finished fourth after a 7-5 loss to Canada in the bronze medal game. Jacobs was selected by Sarnia in the fourth round (72nd overall) of the 2012 OHL Priority Draft.

Indiana missed the playoffs after finishing last in the Eastern Division. Jacobs participated in USA Hockey's Select 17 Camp — scoring 1 goal with 2 penalty minutes in six games.
2013-14: Jacobs returned to Indiana for his second USHL season and skated for the USA in the 2013 U19 World Junior A Challenge. In his first 35 USHL games he was the second-leading scorer amongst Ice defensemen with 5 goals and 13 assists and was +24 with 34 penalty minutes. Indiana was leading the Eastern Conference heading into February. Jacobs had no points nor penalty minutes in four games as the USA captured a gold medal at the WJAC. He participated in the 2013 USA Hockey CCM All-American Prospects game in September and in October 2013 committed to playing hockey at Michigan State in 2014-15. Jacobs was ranked 41st amongst North American skaters in Central Scouting's mid-term rankings prior to the 2014 NHL Draft.
Jacobs has the size and skating ability to be an effective defender with some offensive elements to his game. He can also hit long passes from his own zone and looks to make quick plays in the transition game. His judgement and ambitious nature sometime gets him into trouble but that is something that should improve as he continues to progress.
Jacobs has the prototypical size and skating and passing skills that scouts look for in a pro defenseman. He is headed to Michigan State in September 2014 to play college hockey and should have plenty of time to iron out the inconsistent parts of his game and become the effective two-way defender that his skill set suggests he can be.
