GLENDALE, ARIZ.

And then there were none.

The Tennessee Titans hired Mike Mularkey as head coach on Saturday.

All seven NFL head coaching vacancies are now filled.

Mularkey started this past season as Tennessee’s assistant head coach/tight ends. In November he ascended to interim head coach after Ken Whisenhunt’s dismissal.

Mularkey, 54, previously had been head coach in Buffalo and Jacksonville.

Reports Saturday morning said the job was Mularkey’s to lose after the team interviewed last season’s defensive coordinator, Ray Horton.

The Titans previously interviewed Detroit Lions defensive coordinator Teryl Austin and Jacksonville Jaguars offensive-line coach Doug Marrone.

“The vision Mike presented for our football team during this search as well as the character, integrity, and leadership skills he displayed during the last two months of the season makes him the right coach for the Tennessee Titans,” controlling owner Amy Adams Strunk said in a statement. “Mike is a quality coach and an outstanding person who will help us build this team the right way.

“He has experience as a head coach and a track record for developing young quarterbacks and dynamic offences, and he also brings continuity for our franchise quarterback.”

Alas, Mularkey does not bring a history of head-coaching success. He quit after two seasons with the Bills, in which his teams went 16-18. The Jaguars fired him after one season, when he went 2-14.

The NFL’s other six head-coach vacancies have been filled: Ben McAdoo, New York Giants; Chip Kelly, San Francisco 49ers; Dirk Koetter, Tampa Bay Buccaneers; Hue Jackson, Cleveland Browns; Adam Gase, Miami Dolphins; and, although it reportedly won’t be announced until after the Kansas City Chiefs’ season ends, Bob Pederson, Philadelphia Eagles. Pederson is K.C.’s offensive coordinator.

All but Gase were reported to be a top target of his eventual employer within 24 hours of the vacancy.

MARCHIBRODA DIES: Ted Marchibroda died on Saturday at age 84.

An NFL player in the 1950s with the Pittsburgh Steelers and Chicago Cardinals, Marchibroda coached in the league for four decades, including three stints as head coach (Baltimore Colts, 1975-79; Indianapolis Colts, 1992-95; Baltimore Ravens, 1996-98).

He served as an innovating offensive coordinator with Washington, Chicago, Detroit, Philadelphia and, from 1989-91, with the Buffalo Bills.

Players and coaching friends of Marchibroda’s quickly posted tributes on social media.

“RIP to my 1st HC #Ted Marchibroda,” Hall of Fame running back Marshall Faulk tweeted. “I am grateful for all the lessons about football and life. #goodcoach #betterman”

CHARGERS MULLING: The San Diego Chargers are in some kind of bind.

Do they join the Rams in Los Angeles as early as this season, an option NFL owners gave them Tuesday in Houston? Or do they hammer out a better new-stadium deal and remain in San Diego?

Positives and negatives drape both scenarios.

The Chargers have until March 23 to decide whether to relocate immediately (that is, to join the Rams and play home games at Los Angeles Coliseum through 2018) or, alternatively, until next Jan. 15 to decide to move to L.A. at all. If they choose to remain in San Diego, the Oakland Raiders would have a year to decide whether to take the Chargers’ place in L.A, in partnership with the Rams.

The Chargers could earn considerably more money in L.A., in partnership with Rams owner Stan Kroenke at the $2-billion Taj Mahal of sports stadiums he has received NFL approval to build in Inglewood, to open in 2019.

Plugged-in Californians believe the Chargers would be fortunate to wind up with as high a second-fiddle profile below the Rams in L.A. as the Jets don’t enjoy below the Giants in the Big Apple.

At the Rams’ (re-?)introductory news conference in Los Angeles on Friday, Kroenke said his team has offered the Chargers several “iterations” of partnership proposals. The San Diego Union-Tribune cited sources who say the principle options are to either become equal partners in the Inglewood stadium project (meaning they’d equally pay for it too), or become tenants who would share revenues, including all naming rights.

Another enormous consideration: a mammoth moving cost in the form of a $550-million relocation fee to the league.

Why not stay home and spend that money on a better new stadium in a market they own themselves?

The Union-Tribune reported Friday that San Diego Mayor Kevin Faulconer is willing to negotiate with Chargers president/CEO Dean Spanos while Spanos simultaneously negotiates with Kroenke.

“I’m open to any approach as long as we start talking and it’s sincere,” Faulconer said.

The city has proposed a $1.1-billion stadium in suburban San Diego. The Chargers might prefer a downtown location.

Spanos had cordial telephone conversations Thursday night with Faulconer and another local politician, his first since stadium talks broke off in June, according to the report.

“I said very clearly to him I would welcome the opportunity to get together at his earliest convenience,” Faulconer said. “I told him we can discuss a variety of different options on how to move forward.”

TYROD’S TAKE: While guesting on NFL Networks’ pregame show Saturday, Bills quarterback Tyrod Taylor again showed no apparent disappointment that the team is choosing not to reward him with a new contract.

Taylor just completed his first season as an NFL starter, and played well.

“Ultimately, the management makes that decision,” said Taylor, per the Buffalo News. “I think I’ve shown what I can do. I’m going to continue to get better.”

His contract is due to expire after the 2016 season.

EXTRA POINTS: The New England Patriots gave WR Keshawn Martin a two-year extension ... Baltimore has hired former Minnesota Vikings head coach Leslie Frazier to coach its secondary.
