2026 Outlook
Bethune had a breakout 2025 season after Fred Warner's injury sidelined him. In 8 games as starter, Bethune posted strong stats: 87 tackles (36 solo), 4 TFLs, 1 sack, and 4 passes defensed. Now competing for the starting spot against veteran Fred Greenlaw. Bethune's main weakness is pass coverage (PFF grade of 42.5), but this is expected to improve in his third year. The competition will likely determine who gets close to 100% of defensive snaps. (per 2026 IDP Training Camp Battles to Watch – San Francisco Linebackers)
