Ebner and Patrick Chung are minority owners of Major League Rugby's team New England Free Jacks.

His father, who was Jewish, was a former college rugby player at the University of Minnesota, and Sunday School principal at Temple Shalom in Springfield, Ohio.

He was beaten to death at age 53 during an attempted robbery in November 2008 at the family business, Ebner & Sons auto reclamation in Springfield.

[4][5][6][7][8] In July 2010, his father's killer was sentenced to life in prison for murder, with the possibility of parole after 15 years.

"[13] He said his grandparents continue to be a big influence in his life, and "make sure I keep up with Jewish events and that I remember my origins.

[14][17] Ebner was nicknamed "Leonidas," after a Greek warrior-king hero of Sparta portrayed by Gerard Butler in the movie 300, because of his intense workout regimen, and his beard.

"[27] Asked which special teams unit he enjoyed playing on the most at Ohio State, Ebner's said: "Kickoff, probably.

Pro Football Weekly described him as a player who "races down the field like a bat out of hell, and hunts returners like a heat-seeking missile".

I would probably put him in the, not the all-time top, but maybe in the top-five percent all time of players that I've coached, from where they were in college to how they grew in the NFL.

[He] has adapted in a relatively short amount of time to the knowledge of our defense, to the understanding of opponents' offenses, to instinctiveness and reading and recognition at a position that he plays right in the middle of the field, which is among the most difficult – inside linebacker and safety – where the number of things that can happen is the greatest.

[22]On December 6, 2015, against the Philadelphia Eagles, Ebner attempted a rare onside drop kick on a kickoff after a Patriots touchdown.

He was named to the 2016 AP All-Pro Second Team at the Special Teamer position; he received 12 votes, second only to teammate Matthew Slater's 14.

[43] On November 27, 2017, the Patriots placed Ebner on injured reserve after he tore his ACL on a successful fake punt play during a win against the Miami Dolphins in Week 12, leading to him playing in only nine games for the season, but in those games he had eight special teams tackles which was the most on the team at the time of his injury.

However, after strong showings in the Hong Kong and Singapore events on the World Rugby Sevens circuit, Friday said, "He has a 50:50 chance now but if he stays on this trajectory then it's only going one way and that's up."

Friday added that Ebner played a critical role in improving the team's on-field communication.

According to Friday, one of Ebner's first questions upon arriving at the USA training camp was whether the team had a "comms book."

As a result, the US team fell two points (in scoring differential) short of advancing to medal play; they ultimately finished ninth.

[60] During the Patriots' 2018 offseason, Ebner served as an in-studio analyst for NBC Sports' coverage of the 2018 Rugby World Cup Sevens.

[61] In 2018, Ebner became a minority owner in the New England Free Jacks, a Major League Rugby team, as did his Patriot teammate Patrick Chung.

[62] With support from the New York Giants, he rejoined the USA's men's national sevens team in March 2021 in the hope of being named to the roster for the 2020 Summer Olympics in Tokyo.
