The San Francisco 49ers' defensive line faced scrutiny last season, ranking last in sacks and 31st in pressures. However, former defensive coordinator Robert Saleh remains optimistic about the unit's future. He highlights three young linemen: Mykel Williams, C.J. West, and Alfred Collins, praising their potential and progress. Saleh's perspective is particularly insightful, given his history of developing elite defensive talent. He believes that Collins, a second-round pick, has the potential to be special, citing his forced fumble as a pivotal moment. Williams and West, despite injury and statistical challenges, also show promise. Saleh's confidence in the system and these players underscores the importance of long-term development and the possibility of a turnaround.
