Carroll, 73, is set to return to the NFL sideline as a head coach for the first time since the conclusion of the 2023 regular season.

“In the NFL, though, Carroll has had the upper hand over Harbaugh (6-5), especially in their most recent battles,” Moton wrote. “Though the Chargers are coming off a year in which they clinched a playoff berth with an 11-6 record, Harbaugh probably isn't thrilled to see Carroll back in his conference and division.”
