“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.”

Which means the Super Bowl champion Carroll is now the oldest head coach in the league by far. The San Francisco native will turn 74 in September when the 2025 NFL season begins. The next-oldest coach, Andy Reid, will turn 67 in March — assuming he returns to the Chiefs for another year.

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.
