As the NFL’s fourth-most tenured head coach, Sean McDermott has amassed considerable wealth while coaching the Bills. Since 2017, he has led the team in Western New York, and despite the Week 5 loss, his net worth stands at approximately $20 million.

Sean McDermott, born March 21, 1974, is originally from Omaha, Nebraska, but grew up in Philadelphia.

He attended La Salle College High School, where he excelled in football and wrestling. 

Sean later earned a degree in finance from the College of William and Mary, where he played as an all-conference safety and earned academic honors.

The Football Career Earned Sean McDermott A Fortune And A Successfully Contract Extension

Sean McDermott’s substantial net worth stems from his successful coaching career in the NFL. He earns $8 million annually as head coach of the Buffalo Bills. 

He began as a scouting administrative coordinator for the Philadelphia Eagles, quickly transitioning to coaching roles. 

McDermott served as defensive quality control coach and assistant defensive backs coach before becoming the defensive backs coach. 

Under his leadership, both starting safeties earned Pro Bowl honors for the first time in team history. 

As the defensive coordinator, he led the Panthers to consistently rank in the top ten defensively and reached Super Bowl 50.

Later in 2017, the Buffalo Bills hired McDermott as their head coach, marking a pivotal moment in his career. 

McDermott’s leadership has guided the team to six playoff appearances and four AFC East titles.

As a result of his successes, McDermott’s earnings have continued to grow as he signed a contract extension through 2026, reflecting the team’s confidence in his abilities.
