Jacobs is a smooth skating two-way defenseman. He excels in transition, generating chances by moving the puck up the ice or hitting a streaking forward with a stretch pass. Two other assets he has are hockey sense and his shot. On defense, Jacobs closes off lanes and is willing to commit the body. He suffers an occasional mental lapse and many times his game has been hot or cold. He also has to work on his hands and puck skills.
Jacobs is in his freshman season at Michigan State University in 2014-15. One of four NHL draftees on the blueline for the rebuilding Spartans program, the 18-year-old is seeing a lot of ice time and has been one of the team's top defensemen along with junior Travis Walsh. Still developing in terms of his technical skills and positioning, as well as adding size and strength, he will likely use most of his NCAA eligibility before moving on to the pro game. Long-term he is projects to one day being a middle pairing defender with the ability to contribute to the attack.
