2025 Fantasy Outlook

McDuffie's role has steadily increased since his rookie season of 2021, and the Packers locked him up for two more years before free agency got underway. He should occupy a starting spot in Green Bay's base defense, but fellow linebackers Edgerrin Cooper and Quay Walker profile better from a fantasy perspective. Read Past Outlooks

Double-digit tackles Sunday

LBGreen Bay Packers

November 17, 2025

McDuffie recorded 11 total tackles (five solo), including 0.5 sacks, in Sunday's 27-20 win over the Giants.

ANALYSIS
Quay Walker (shoulder) played just 36 defensive snaps due to an injury in the Week 11 win, allowing McDuffie to operate as one of the Packers' starting inside linebackers. He notched his first double-digit stop performance of the season while leading Green Bay's defense in total tackles. If Walker is unable to suit up in the Week 12 matchup against the Vikings, McDuffie will likely draw a start alongside Edgerrin Cooper.

Past Fantasy Outlooks

2024

2023

McDuffie's role increased significantly in 2023, and he played nearly half of Green Bay's defensive snaps while doubling the 43 tackles he recorded the year before. He'll remain in the mix for a Packers team shifting to a 4-3 defense, but leading tackler Quay Walker is back, and Green Bay drafted fellow linebacker Edgerrin Cooper in the second round, meaning McDuffie is the most likely to be subbed out in passing situations.

McDuffie has become a quality depth linebacker for the Packers, and he recorded a 12-tackle game in 2022. However, with De'Vondre Campbell and Quay Walker locked into the starting middle linebacker spots, McDuffie is slated to remain a reserve.
