Dean Spanos has decided he isn’t “All In” anymore on Brandon Staley and Tom Telesco leading the Los Angeles Chargers.

The Chargers owner fired Staley as coach and Telesco as general manager Friday morning after one of the worst losses in franchise history.

Los Angeles made the playoffs last season but is one of this year’s biggest disappointments at 5-9, with losses in five of their last six games. The Bolts dropped into last place in the AFC West after Thursday night’s 63-21 loss at Las Vegas.

It was the most points allowed in franchise history and the 42-point margin was the third-worst.

Spanos thanked Staley and Telesco in a statement for their hard work, dedication and professionalism, but he did not mince words on in why the move was made with three games remaining in the regular season.

“Doing nothing in the name of continuity was not a risk I was willing to take. Our fans have stood strong through so many ups and downs and close games. They deserve more. Frankly, they’ve earned more,” he said.

Giff Smith will serve as the interim head coach and JoJo Wooden as interim general manager. Los Angeles’ next game is against Buffalo on Dec. 23.

Smith, the outside linebackers coach, has been with the organization for eight seasons and was the only position coach retained by Staley when he was hired in 2021. Wooden was one of Telesco’s first front office hires in 2013 and is the director of player personnel.

Run game coordinator/defensive line coach Jay Rodgers was also fired.

Staley — who had an overall record of 24-25 — is the third NFL coach to be fired this season, joining Josh McDaniels of the Raiders and Carolina’s Frank Reich.

It is the first time since 1998 that the Chargers have made an in-season coaching move.

Telesco had been the general manager since 2013. The team only made three playoff appearances under his tenure and were 86-95 overall.

While Staley had been confident about his job security in the past, Thursday night’s titanic defeat had him questioning his future. He said “I don’t know” when asked if he would still be leading the Chargers on Friday.

However, Staley wasn’t lacking in confidence and said he should remain in charge.

“I know what I’ve done here for three years, and I know what I’ve put into this. I know what we’re capable of. I know the type of coach that I am, and I believe in myself,” he said.

Staley’s questionable late-game decisions and aggressive go for it approach on fourth downs drew many critics. The Chargers were 6-12 in games decided by three points or less, including 0-5 this season.
