An ex-NFL player going back to school post-football career is a rarity. It’s even more rare for a former professional football player to earn his MBA at Harvard Business School, one of the most prestigious schools in the world. That’s the type of person Domonique Foxworth is—one of a kind.

The former University of Maryland cornerback’s involvement with the union started early. Just two years after being drafted by the Denver Broncos in 2005, Foxworth was elected the club’s Player Rep. One year later, he became the youngest Vice President of the Executive Committee at the age of 25.

Although Foxworth struggled with injuries on the field, he was a strong voice for the NFLPA during the 2011 lockout. Well-liked and undeniably intelligent, he was elected president without opposition the next year. Although he announced his retirement from football that same year, Foxworth continued his presidency until 2014, when current President Eric Winston succeeded him.

After football, Foxworth attended Harvard Business School and went on to become the Chief Operating Officer for the National Basketball Players Association. Foxworth is currently a Senior Writer for ESPN's The Undefeated.
