Boston College filled its coaching vacancy with one of the nation’s top assistant coaches. Jeff Hafley, Ohio State’s co-defensive coordinator and defensive backs coach, will take over for Steve Adazzio, with whom the the Eagles parted ways on Dec. 1.

Hafley, 40, led a Buckeyes defense that ranked second in the country in both total yards allowed and passing yards allowed per game. Before joining Ohio State, Hafley spent seven years in the NFL coaching defensive backs for the Buccaneers, Browns and 49ers.

Hafley will remain with Ohio State through the duration of the College Football Playoff.

Adazzio went 44-44 in seven seasons at Boston College, including 6-6 this past season. The Eagles will face No. 21 Cincinnati on Jan. 2 in the Birmingham Bowl. It’s unclear who will coach the team during the game.

Here’s a look at who’s hiring and who could be hired elsewhere:

The jobs

Appalachian State

Departed: Eli Drinkwitz (11-1 in one season)

Drinkwitz has agreed to replace Barry Odom at Missouri.

Hired: The Winston-Salem Journal reports that Shawn Clark, the Mountaineers’ offensive line coach the past four seasons who was named interim head coach upon Drinkwitz’s departure, will ascend to the top job permanently.

Arkansas

Fired: Chad Morris (4-18 in less than two seasons)

Hired: Sam Pittman

A longtime assistant, including a stint with the Razorbacks from 2013 to 2015, the 58-year-old Pittman is getting his first chance to run a major program. (He was head coach at Kansas’s Hutchinson Community College in 1992 and 1993.) He comes over from Georgia, where he was a top assistant to Kirby Smart and oversaw the offensive line.

Boston College

Fired: Steve Addazio (44-44 in seven seasons)

Addazio went 7-6 or 7-5 in five of his seven seasons in Chestnut Hill and achieved bowl eligibility in six of them but still was fired.

Hired: Hafley

“Jeff’s shown throughout his coaching career he is a tremendous leader with high integrity and a gift for teaching," Boston College Athletics Director Martin Jarmond said in a statement. "His passion, leadership and ability to recruit and develop student-athletes make him the right fit to lead Boston College to greater heights on and off the field.”

Colorado State

Out: Mike Bobo (28-35 in five seasons)

Hired: Addazio

“Throughout his career, Coach Addazio has been committed to the holistic development of student-athletes and of the programs he has led,” Colorado State Director of Athletics Joe Parker said in a statement. “He has focused on crafting cultures where his students thrive on the field and in the classroom. We look forward to Coach Addazio leading our football team as we strive to be the preeminent program in the Mountain West.”

Florida Atlantic

Departed: Lane Kiffin (26-13 in three seasons)

Kiffin was hired to replace Matt Luke at Mississippi.

Hired: Willie Taggart

Taggart, 43, was out of work for only about six weeks after he was fired by Florida State with three games left on the Seminoles’ schedule. He posted a 9-12 record in Tallahassee after coming over from Oregon, where he went 7-5 in one season. He spent four seasons at South Florida before that, going 24-25, and he was considered a candidate to return there and fill a recent vacancy, before the school went with former Clemson assistant Jeff Scott.

Florida State

Fired: Willie Taggart (9-12 in less than two seasons)

Hired: Mike Norvell

Norvell will bring his predilection for high-scoring offenses from Memphis, where only Oklahoma, Ohio State and Alabama averaged more points per game than the Tigers over his four seasons. Memphis went 38-15 in that span and won three straight American Athletic Conference West division titles, and on Saturday the 17th-ranked Tigers won the AAC championship with a 29-24 victory over No. 20 Cincinnati.

Fresno State

Stepping down: Jeff Tedford

Tedford, 58, stepped down Friday because of health reasons, according to multiple reports. He’s gone 26-14 in three seasons at his alma mater — 22-6 his first two seasons — with two bowl wins. Tedford previously had heart problems in 2014 while an assistant for the Tampa Bay Buccaneers.

Memphis

Departed: Norvell, to Florida State.

Hired: Ryan Silverfield, the Tigers’ offensive line coach the past four seasons and the team’s interim head coach after Norvell’s departure, is expected to be named Memphis’s permanent head coach on Friday, according to the Commercial Appeal.

Mississippi

Fired: Matt Luke (15-21 in three seasons)

Hired: Lane Kiffin

Lane Kiffin is headed back to the SEC, taking over a struggling Ole Miss program in desperate need of a jolt. Kiffin, whose Florida Atlantic team romped to a Conference USA title on Saturday, started his college head coaching career in the SEC at Tennessee before moving on to USC and then Florida Atlantic. (He also served as Alabama’s offensive coordinator for three years before taking the Florida Atlantic job.) He spent three seasons in Boca Raton, racking up a 26-13 record with Florida Atlantic and twice winning the Conference USA title. The Owls crushed UAB, 49-6, on Saturday.

Missouri

Fired: Barry Odom (25-25 in four seasons)

Hired: Eli Drinkwitz

Appalachian State Coach Eli Drinkwitz has reached an agreement to coach the Tigers and was finalizing a deal Sunday, per ESPN. The 36-year-old Drinkwitz, whose coached the Mountaineers for just one season, is the second-youngest coach in FBS, older than only Oklahoma’s Lincoln Riley. Drinkwitz reportedly will make $4 million per year, a more than 400 percent raise over his previous salary.

New Mexico

Resigned: Bob Davie (35-64 in eight seasons)

Davie led the Lobos to a nine-win season and a bowl victory in 2016 but went 8-28 in three seasons since then.

Old Dominion

Resigned: Bobby Wilder (77-56 after 11 seasons)

Wilder, who shepherded the Monarchs’ program into existence and then oversaw its ascendance from FCS to FBS, stepped down Monday after three straight losing seasons, the final one a 1-11 campaign.

Hired: Ricky Rahne

Rahne spent the last six seasons at Penn State, the last two as the Nittany Lions’ offensive coordinator.

Rutgers

Fired: Chris Ash (8-32 in less than four seasons)

Hired: Greg Schiano

After initial negotiations fell apart, Rutgers announced Sunday that Schiano would return to the program he coached from 2001 to 2011, finding success rarely seen on the Banks of the Old Raritan (bowl appearances in six of his final seven seasons and a No. 7 national ranking in 2006). The New Jersey native has a massive task ahead of him, as Rutgers is in no way close to competitive in the Big Ten.

South Florida

Fired: Charlie Strong (21-16 in three seasons)

Hired: Jeff Scott

Scott, who turns 39 later this month, was plucked from Clemson, though he reportedly will continue to help the Tigers as they compete in the College Football Playoff. A Florida native and Clemson graduate, he has worked on Clemson’s football staff since 2008, rising through the ranks to become the co-offensive coordinator/wide receivers coach for a perennial powerhouse. Scott is also credited with recruiting and coaching several of the standout players who have fueled the Tigers’ dominance.

UNLV

Fired: Tony Sanchez (20-40 in five seasons)

With a move to the new Oakland Raiders stadium on the horizon, UNLV decided to look elsewhere after winning no more than five games in Sanchez’s tenure.

Hired: Marcus Arroyo

Arroyo was Oregon’s offensive coordinator the past three seasons, helping the Ducks win the Pac-12 title in 2019.

UTSA

Fired: Frank Wilson (19-29 in four seasons)

The Roadrunners won’t be hiring former Baylor coach Art Briles. Athletic Director Lisa Campos said he isn’t a candidate because of how he handled sexual assault allegations with the Bears.

Hired: Jeff Traylor

Traylor most recently was associate head coach and running backs coach at Arkansas. He has a long history in Texas, having coached Gilmer High School in East Texas for 14 years earlier this century.

Washington

Stepping down: Chris Petersen (54-26 in six seasons)

Promoted to head coach: Jimmy Lake

Washington stunned the college football world, announcing that Petersen is stepping down to “recharge,” as he said in a statement. Lake, who garnered interest from Colorado last year, has been on Petersen’s Washington staff since 2014 and was promoted to co-defensive coordinator in 2016.

Staying put

Kevin Sumlin, Arizona: Athletic Director Dave Heeke said Saturday night that Sumlin — 9-15 in two seasons in Tucson and coach of a team that lost seven straight games to end the season — is “our head football coach” heading into the 2020 season. Sumlin’s $10 million buyout might have something to do with that.

Randy Edsall, Connecticut: Despite records of 2-10, 1-11 and 3-9 in his return to Storrs, U-Conn. Athletic Director David Benedict said Edsall will be back in 2020.

Tom Allen, Indiana: Indiana announced Friday that Allen has a new seven-year, $27.3 million deal that will run through the 2026 season.

Matt Campbell, Iowa State: Iowa State announced Tuesday that Campbell had signed a contract extension through the 2025 season. He reportedly had been targeted by a few college teams — Florida State and Arkansas, specifically — and attracted the attention of NFL teams.

Joe Moorhead, Mississippi State: A 6-6 record and a bowl game were enough to keep Moorehead in Starkville for another season.

Doug Martin, New Mexico State: Despite a 22-63 record in Las Cruces, Martin will be back for his eighth season in 2020, AD Mario Moccia said Tuesday.

Clay Helton, Southern Cal: Speculation about Helton’s future and the ripple effects his possible firing could have — considering that the Trojans’ job is one of the most desirable in college football — continued into Wednesday before AD Mike Bohn announced that the 47-year-old coach would stay on, at least for the 2020 season.

Derek Mason, Vanderbilt: Athletic Director Malcolm Turner announced last month that Mason will be back in 2020 even though he has yet to field an above-. 500 team in his six seasons. The Commodores finished 3-9 in 2019.

Mike Leach, Washington State: Leach seemingly is a perennial candidate for open jobs, but Washington State announced Thursday that it has extended his contract through the 2024 season.
