Stevenson Isaiah McDuffie is an American professional football linebacker for the Green Bay Packers of the National Football League (NFL). Standing 6 ft 1 in and weighing about 227 lb, he plays the linebacker position and wears jersey number 58 for the Packers. Since being drafted in 2021, he has grown into a regular contributor on the Green Bay defense, eventually earning a full-time starting role. A graduate of Boston College, McDuffie is recognized for his football intelligence, tackling consistency, and leadership at the second level of the defense.
Early Life and Background
Stevenson Isaiah McDuffie was born on July 21, 1999, in Buffalo, New York, in the United States. He grew up in the same western New York community that has produced a long line of football talent. McDuffie attended Frederick Law Olmsted High School PS156 in Buffalo, but because the school did not field a football team, he played his high school football for the Bennett Tigers. Wearing the Bennett colors, he developed as both a running back and a linebacker, gaining the experience that would later define his college recruitment.
During his time at Bennett, McDuffie earned a series of accolades, including the prestigious Connolly Cup in 2016, an award given annually to the best high school football player in Western New York. The recognition highlighted his two-way ability and his value on every snap. His play at Bennett helped him build the foundation that would carry him to the next stage of his career at the college level.
Path to American Football
McDuffie’s path to a college career began in July 2015, when he verbally committed to play football at Syracuse University. Less than a year later, in May 2016, he de-committed from Syracuse and chose Boston College instead. The decision set the course for his development as a linebacker in a defensive system known for producing NFL-ready players.
He enrolled at Boston College and played for the Eagles from 2017 through 2020, appearing in multiple seasons under the Atlantic Coast Conference banner. In his 2020 campaign, McDuffie was recognized as a Second-team All-Atlantic Coast Conference selection, validating his consistency and playmaking ability at the position. Following that senior season, he declared for the 2021 NFL Draft, where his college resume drew the attention of league scouts.
Isaiah McDuffie Career
Early Career (2017–2020)
McDuffie’s early career took place entirely at Boston College, where he spent four seasons working his way into a major role in the Eagles’ defense. As he grew into the program, he added bulk to his frame and refined his instincts as a linebacker, which prepared him to take on a full-time starting role in his final college seasons. The 2020 Second-team All-ACC nod was the clearest sign of his development.
That recognition helped build his draft profile, and he was selected by the Green Bay Packers in the sixth round of the 2021 NFL Draft, 220th overall. He signed his rookie contract on May 14, 2021, officially beginning his professional career in Green Bay.
Green Bay Packers Breakthrough (2021–2023)
McDuffie spent his first NFL seasons working primarily in a rotational role behind established veterans. Heading into 2022, he was listed as the fourth linebacker on the depth chart, behind De’Vondre Campbell, Quay Walker, and Krys Barnes. He saw his first significant action on October 30, 2022, during a Week 8 loss to the Buffalo Bills, when injuries and an ejection forced the Packers to rely on him in expanded snaps.
As injuries reshuffled the linebacker room, McDuffie stepped in as a primary defensive playcaller alongside the recently signed Eric Wilson. In Week 9 against the Detroit Lions, he started alongside Walker and recorded five tackles while earning a Pro Football Focus grade of 91.1, a strong early indicator of his readiness. Over the next seasons, he continued to develop and earn additional responsibility within the defensive scheme.

McDuffie’s 2024 campaign marked his emergence as an every-down player for the Packers. He started all 17 regular season games that year and ranked second on the team in tackles, cementing his status as a core member of the defense.

Following the 2024 season, the Packers re-signed McDuffie on March 3, 2025, rewarding his production and signaling a continued role within the organization. With his size, tackling volume, and growing experience as a communicator on the field, he remains a key figure in the team’s defensive plans.
