Charlie Weis Jr. comes to LSU with numbers that should immediately get the attention of Tiger fans. He is only 33 years old entering the 2026 season, yet this is already his ninth season as an FBS offensive coordinator. Six times as a play caller, his offenses have averaged at least 445 yards and more than 30 points per game. At Ole Miss, his offenses finished third in the SEC in total offense in 2022 and 2023, then led the conference in both 2024 and 2025.

The final two seasons were especially impressive. Ole Miss averaged a school record 526.5 yards per game in 2024, second nationally, while scoring 38.6 points per game. In 2025, the Rebels averaged 489.7 yards and 36.9 points per game while producing a school record 7,345 yards of total offense. They also led the SEC with 313.3 passing yards per game and finished the season with 65 offensive touchdowns.

That is the offensive résumé Lane Kiffin brought with him to Baton Rouge.

Weis joined LSU in December 2025 as offensive coordinator after four seasons in the same role at Ole Miss. He has now spent six seasons as Kiffin’s offensive coordinator, two at Florida Atlantic and four at Ole Miss. Their partnership has developed into one of the most productive offensive combinations in college football.

Now they get to see what that system can do at LSU.

Growing Up Around Football

Football has been part of Weis’ life almost from the beginning. Born April 29, 1993, Weis is the son of longtime NFL and college coach Charlie Weis. His father served as offensive coordinator for the New England Patriots during three Super Bowl championship seasons and later became head coach at Notre Dame and Kansas.

Charlie Weis Jr. began gaining coaching experience while he was still a teenager. In 2011, he worked in offensive quality control at Florida with a focus on wide receivers. From 2012 through 2014, he served as an undergraduate team manager at Kansas while his father was the head coach.

His responsibilities went far beyond ordinary student-manager work. Weis helped position coaches conduct drills, ran meetings for quarterbacks, running backs and wide receivers, and assisted with opponent breakdowns. In the summer of 2014, he also worked as a volunteer training camp intern with the New England Patriots, assisting the offensive staff and tight ends coach Brian Daboll.

Weis graduated from Kansas in 2015 with a degree in psychology and a minor in sociology.

His next stop placed him around two coaches who would have an enormous influence on his career: Nick Saban and Lane Kiffin.

Learning Under Saban and Kiffin

Weis joined Alabama as an offensive analyst in 2015. Saban was the head coach, and Kiffin was running the offense.

For a young coach interested in offensive football, it was about as valuable an education as he could have received.

Weis worked with Alabama’s quarterbacks and running backs, studied opposing defenses and assisted with in-game adjustments. He also worked directly with Derrick Henry during Henry’s 2015 Heisman Trophy season.

Alabama went 30-2 during Weis’ two seasons in Tuscaloosa. The Crimson Tide won consecutive SEC championships in 2015 and 2016 and captured the national championship following the 2015 season.

Weis was learning how an elite college football operation worked while also developing a relationship with Kiffin that would shape much of his career.

After Alabama, Weis spent 2017 as an offensive analyst with the Atlanta Falcons.

Then Kiffin gave him a much larger responsibility.

He handed him an offense.

Producing Immediately at Florida Atlantic

Kiffin hired Weis as Florida Atlantic’s offensive coordinator and quarterbacks coach for the 2018 season. Weis was only 25 years old when the season began, making him one of the youngest coordinators in major college football.

His age did not stop the production.

FAU averaged 478.8 yards per game in 2018, ranking 14th nationally. The Owls averaged 241.8 rushing yards per game, good for 13th in the country.

Running back Devin Singletary rushed for 1,348 yards and scored 22 rushing touchdowns. Those 22 scores ranked second nationally.

The offense became even more complete in 2019.

FAU averaged 36.4 points and 448.6 yards per game. The Owls ranked 14th nationally in scoring offense and won the Conference USA championship.

Quarterback Chris Robison passed for 3,701 yards and 28 touchdowns. Tight end Harrison Bryant caught 65 passes for 1,004 yards and seven touchdowns, won the John Mackey Award and became a unanimous first team All American.

Weis had demonstrated that he could coordinate a championship offense.

He was only 26 years old.

Two More Years as a Play Caller

Weis moved to South Florida as offensive coordinator and quarterbacks coach in 2020 and remained there through the 2021 season.

The Bulls struggled as a team, but the experience gave Weis two additional years calling an offense and developing players. One of the bright spots was running back Jaren Mangham, who rushed for a team leading 671 yards and scored 15 rushing touchdowns in 2021.

Those 15 touchdowns ranked third in the American Athletic Conference and tied for second in USF single season history at the time.

Then Kiffin called again.

This time, the opportunity was in the SEC.

Building the Ole Miss Offense

Weis became Ole Miss’ offensive coordinator and quarterbacks coach in 2022.

The results were immediate.

Ole Miss averaged 496.4 yards per game, ranking eighth nationally and third in the SEC. The Rebels led the SEC and ranked third nationally with 256.6 rushing yards per game.

They rushed for a school record 3,336 yards.

That season also began Weis’ work with Jaxson Dart, a relationship that would become one of the biggest success stories of his coaching career.

Dart continued developing in 2023, passing for 3,364 yards, 23 touchdowns and only five interceptions. His 162.4 passing efficiency rating was the second best single season figure in Ole Miss history at the time.

The Rebels finished 11-2, defeated Penn State in the Peach Bowl and recorded the first 11 win season in program history.

Ole Miss averaged 461.9 yards per game, ranking 13th nationally, while committing only seven turnovers, the fewest in the FBS.

Then the offense went to another level.

A Record Setting 2024 Offense

Ole Miss produced one of the greatest offensive seasons in school history in 2024.

The Rebels averaged a school record 526.5 yards per game, ranking second nationally.

They averaged 350.8 passing yards per game, also second nationally, and scored 38.6 points per game, ranking third.

Ole Miss established school records with 6,845 yards of total offense, 4,561 passing yards and 7.3 yards per play. The Rebels also led the FBS with a 176.6 team passing efficiency rating.

For his work as a play caller, Weis received the Graphite Award as the SEC’s top offensive play caller.

At the center of the offense was Dart.

He passed for 4,279 yards while completing 69.3 percent of his passes. His 180.7 passing efficiency rating and 10.8 yards per attempt led the nation.

Dart also led the country with 4,774 yards of total offense.

By the end of his Ole Miss career, Dart had established school career records with 10,617 passing yards, 12,115 yards of total offense and 28 victories as the starting quarterback.

The New York Giants selected him in the first round of the 2025 NFL Draft.

That development was significant for Weis. He was not simply coordinating an offense that accumulated yards. His quarterback had developed into a first round NFL Draft pick.

A New Quarterback and More Records

Dart left for the NFL, but the Ole Miss offense did not disappear.

That may be one of the strongest arguments for Weis as an offensive coach.

In 2025, Division II transfer Trinidad Chambliss took over as the starting quarterback in Week 3 and quickly became one of the biggest breakout stories in college football.

Chambliss passed for 3,937 yards and 22 touchdowns. He earned SEC Newcomer of the Year honors and second team All SEC recognition.

Meanwhile, Ole Miss continued piling up yards.

The Rebels averaged 489.7 yards per game and 313.3 passing yards while scoring 36.9 points per game. They finished with a school record 7,345 yards of total offense and 4,700 passing yards.

Ole Miss reached 400 yards of offense in 13 games and topped 500 yards five times.

The Rebels finished 13-2, defeated Tulane in the opening round of the College Football Playoff, beat Georgia in the quarterfinals and advanced to the national semifinals before losing to Miami.

Different quarterback.

Different personnel.

Same explosive production.

Following Kiffin to LSU

When Kiffin left Ole Miss for LSU following the 2025 regular season, Weis eventually followed him to Baton Rouge.

LSU officially announced Weis as its offensive coordinator in December 2025. He was among eight members of Kiffin’s Ole Miss staff who followed the new head coach to LSU.

For Weis and Kiffin, Baton Rouge represents the continuation of a partnership that now stretches across Alabama, Florida Atlantic, Ole Miss and LSU, although Weis served as Kiffin’s actual offensive coordinator at FAU and Ole Miss.

Kiffin remains the architect of the overall offensive philosophy, but Weis has established his own résumé as a play caller and quarterback developer.

At LSU, Weis will coordinate an offense inside a program accustomed to elite quarterback play and explosive production.

The expectations will be enormous.

His history suggests he will welcome them.

Football and Family

Weis comes from one of football’s best known coaching families, but he has built a substantial résumé of his own. His father spent decades coaching in college football and the NFL, including his three Super Bowl winning seasons as New England’s offensive coordinator.

Charlie Weis Jr. and his wife, Jen, have three children: Mav, Axe and Cannon. Despite being only 33 entering his first LSU season, Weis has already spent more than a decade working inside college and professional football organizations while balancing the demands of coaching with raising a young family.

That combination of youth and experience is unusual. Weis is younger than many coaches who are only beginning to receive coordinator opportunities, yet he has already been an FBS offensive coordinator for eight seasons before beginning his ninth at LSU.

Now He Has LSU

The most exciting part for LSU fans is not simply where Weis has coached.

It is what his offenses have done.

At least 445 yards and 30 points per game six times as a play caller.

478.8 yards per game at FAU in 2018.

A Conference USA championship in 2019.

A school record 3,336 rushing yards at Ole Miss in 2022.

The first 11 win season in Ole Miss history in 2023.

A school record 526.5 yards per game in 2024.

A school record 7,345 yards of total offense in 2025.

Four consecutive Ole Miss seasons finishing among the top three in the SEC in total offense.

Two straight seasons leading the conference.

And two very different quarterbacks producing elite seasons under his direction.

Those numbers are the reason Charlie Weis Jr. matters at LSU.

He is young, but he is not inexperienced. He has worked in the NFL, learned under Nick Saban, spent years alongside Lane Kiffin, developed a first round quarterback and coordinated record setting offenses against SEC defenses.

Now that offense is coming to Tiger Stadium.

LSU did not hire Kiffin and Weis to play cautiously. Their history points toward aggression, explosive plays, quarterback development and an offense designed to put constant pressure on a defense.

Kiffin brings the philosophy.

Weis knows how to help turn it into production.

After years of breaking offensive records together, they finally get to see what their system can do with LSU across their chests.
