Jeff Potter


Jeff Potter

Jeff Potter is the founder and president of Potter Sports Group, a full service sports agency. Jeff also founded the Fort Wayne Mad Ants of the NBA Development League and served as its CEO and General Manager from 2007 until 2015, when he sold the franchise to the Indiana Pacers.

Jeff grew up in the Pacific Northwest, where he graduated from Redmond High School in Redmond, Washington. Jeff attended the University of Oregon on a basketball scholarship and captained a team that returned the Ducks to the NCAA Tournament for the first time in 35 years. From there, he played professionally overseas for six seasons before returning to the University of Oregon for law school. After completing his final year of law school at Northwestern University School of Law, Jeff became a prosecutor for the Cook County State’s Attorney’s Office in Chicago.

In 2007, Jeff partnered with John Zeglis, the retired Chairman and CEO of AT&T Wireless Services, to create the Fort Wayne Mad Ants. Jeff built the team from the ground up and was responsible for every aspect of the franchise – from the team’s finances, sales, and marketing to community relations and human resources. Under his leadership, the Mad Ants became one of the most successful and recognizable teams in the NBA Development League.

Beyond his extensive involvement with the franchise’s business operations, from 2007 to 2015 Jeff also ran the Mad Ants’ basketball operations as the team’s general manager. Jeff was responsible for all employment decisions regarding coaching staffs and players, including numerous Mad Ant players who have received NBA call-ups and who have played on NBA summer league teams. His greatest triumph was building the team that brought home the 2013-2014 NBA Development League Championship and nearly repeating the next year by reaching the 2014-2015 NBA Development League Finals. His experience as a professional basketball player, combined with his legal education and business experience, helped Jeff greatly in addressing the myriad of issues that a general manager must face and played an important part in putting together championship teams.

Jeff has also been influential in making critical changes to the NBA Development League. Working closely with the NBA’s Adam Silver and NBA Development league leadership, Jeff helped create the Owners’ Executive Committee and, as the leading member of the committee, negotiated several fundamental business model changes on behalf of all D-League franchises. These essential improvements were responsible for solidifying the long term survival and eventual success of the NBA Development League. Further, as part of his duties on the executive committee, Jeff created and wrote the charter for the NBA Development League’s Basketball Rules Committee, of which he was a long serving member. Finally, as part of the Owner’s Executive Committee, Jeff helped create and negotiated a profit sharing program to enable NBA Development League franchises to participate in the financial success of the NBA Development League’s quickly growing operations.

In 2015, Jeff sold the Fort Wayne Mad Ants franchise to the Indiana Pacers and thereafter served as the Mad Ants president of business operations to assist in the transition before striking out on his own with The Potter Group, a business consulting firm, in 2016.

Jeff is also very active in the community, serving on the board of directors of the Mad Anthony’s Children’s Foundation. Jeff has also served on the Embassy Theater board (where he chaired the audit committee and served on the finance committee), the Trine University Business School Advisory Board, and the Indiana State Chamber of Commerce board.
Jeff has been married to Julie since 2004, and they have three children — Sydney, Alexander, and Zoe.

One thing I can say about JP is his word is his bond. I played for him for five years and worked as a coach for him for two. He always keeps his word and is totally honest with you, even if it something you do not necessarily want to hear. That’s hard to find in this business. He has helped me become the man I am today.
