Townsend, a rising star in coaching circles, has emerged as a standout contender, while Saleh, who previously served as the 49ers’ defensive coordinator from 2017 to 2020, could make a high-profile return to San Francisco.

Deshea Townsend’s work with the Detroit Lions has not gone unnoticed. As the passing game coordinator, Townsend played a pivotal role in helping the Lions’ defense improve significantly in 2024, particularly in defending against the pass. Under his guidance, Detroit’s secondary went from being a liability to a strength, helping the team earn a playoff berth and a reputation as one of the league’s most resilient defenses.

Townsend’s rapid rise has sparked speculation about the development of a potential coaching tree under Lions head coach Dan Campbell. Fans are taking notice, with one asking on Twitter, “Is there going to be a Dan Campbell coaching tree?”

While Townsend lacks experience as a full-time defensive coordinator, his ability to connect with players and implement effective schemes has earned him high praise. For a 49ers defense that has long been defined by aggression and versatility, Townsend could bring a fresh perspective while maintaining the unit’s dominance.

Robert Saleh’s name carries weight in the Bay Area. During his tenure as San Francisco’s defensive coordinator, Saleh established the 49ers as one of the league’s premier defenses, culminating in a Super Bowl appearance in the 2019 season.
