Texas A&M doesn’t have a long history in the SEC, but the Aggies have long been one of the proudest programs in college football.

Texas A&M claims three national championships, and though the Aggies haven’t won it all since 1939, they have been a consistent winner. A&M won 18 conference championships (17 as a member of the Southwest Conference) including at least one in every decade from the 1910s to the 1990s.

But which Texas A&M football teams were the best in school history? We take a look at the five greatest Aggies squads of all-time.

Honorable Mention

1927: 8-0-1 (4-0-1), Southwest Conference Champions

One of three Texas A&M football teams to claim a national title, the 1927 Aggies were a dominant squad that ranked in the top seven in the country in both scoring offense (29.1 points per game) and scoring defense (3.6 points allowed per game). A&M shut out five opponents, but one was a scoreless tie against TCU that ruined an otherwise perfect season.

1985: 10-2 (7-1), Southwest Conference Champions

Under the direction of head coach Jackie Sherrill, the 1985 Aggies didn’t make an appearance in the AP Top 25 until Nov. 19, but quickly rose after beating four ranked opponents in their final five games. That stretch included a dominant 42-10 win over No. 18 Texas in the regular-season finale and a 36-16 victory over No. 16 Auburn in the Cotton Bowl.

1992: 12-1 (8-0), Southwest Conference Champions, No.7 Final Ranking

Texas A&M came very close to winning a share of the national championship in ’92, but played a weak regular season schedule that featured just one ranked opponent (none in conference play). After a 12-0 start, No. 5 Notre Dame blasted the Aggies 28-3 in the Cotton Bowl.

1998: 11-3 (7-1), Big 12 Champions

Playing one of the toughest schedules in the nation, which included four opponents ranked in the top three of the AP Top 25, Texas A&M won the only Big 12 Conference title in school history in 1998. In fact, the ’98 Aggies were the last in program history to earn a conference crown.

5. 1994: 10-0-1 (6-0-1), Ineligible for SWC Championship, No. 8 Final Ranking

Best known for his Wrecking Crew defense, Texas A&M head coach R.C. Slocum led Texas A&M to one of its most successful periods in school history from 1989-2002. With a defense that allowed just 13.4 points per game, which ranked fifth in the nation, the undefeated 1994 Aggies were arguably Slocum’s best team.

Texas A&M opened the season with an 18-13 victory over LSU in Tiger Stadium and continued a difficult non-conference regular season schedule with an impressive 36-14 win over No. 15 Oklahoma. Unfortunately, the country missed out on those high-profile matchups because the Aggies were banned from TV as a result of NCAA sanctions.

A&M was also ineligible for the Southwest Conference title and the postseason, which was a shame because the team was easily the best in the league. Every other team in the competitive SWC lost at least three conference games.

It’s possible that the sanctions led to boredom, as the Aggies were inexplicably tied 21-21 by SMU in Week 7 during a neutral site meeting in San Antonio. The Mustangs finished the season 1-9-1 overall and were winless in conference play.

4. 2012: 11-2 (6-2) No. 5 Final Ranking

After decades of great success, Texas A&M fell into a pattern of mediocrity in the final years of the R.C. Slocum era, and failed to get out of it under Dennis Franchione or Mike Sherman. After just one top 20 finish in 13 years (No. 19 in 2010), the Aggies burst through in a big way in 2012 under first-year head coach Kevin Sumlin and electric Heisman-winning quarterback Johnny Manziel.

In the program’s first game as a member of the SEC, unranked A&M lost a nail biter to No. 24 Florida, but then rolled up six straight wins until a loss to No. 6 LSU 24-19. The respectable start earned the Aggies a spot in the Top 25, and the team climbed into the Top 10 after headlining victories over No. 17 Mississippi State and No. 1 Alabama. The 29-24 victory over the Crimson Tide in Tuscaloosa was the national coming-out party for Johnny Football, who rewrote the school record book with 3,706 passing yards and 26 touchdown passes in addition to 1,410 rushing yards and 21 TDs on the ground as a redshirt freshman.

A dominant 41-13 victory over No. 12 Oklahoma in the Cotton Bowl gave the Aggies their first Top 5 finish in the AP poll since 1956.

3. 1956: 9-0-1 (6-0), Southwest Conference Champions, No. 5 Final Ranking

Many great coaches have come through College Station, including arguably the greatest head coach in college football history. Bear Bryant posted a 25-14-2 record at Texas A&M that was weighed down by a 1-9 record in 1954. Just two years later, the Aggies won the Southwest Conference with a perfect 6-0 record in league play. That included victories over No. 4 TCU and No. 8 Baylor. The only thing standing between A&M and a potential share of a national championship was a 14-14 tie at Houston in Week 4.

A&M ranked in the top 10 in the nation in scoring defense, having allowed just 8.1 points per game. The offense was led by 1957 Heisman Trophy winner John David Crow, who paced the team with six rushing touchdowns and three receiving TDs.

2. 1919: 10-0 (4-0), Southwest Conference Champions, National Champions

Long before the Wrecking Crew, the 1919 Texas A&M defense posted the greatest statistical season in school history. No opponent scored a point against the Aggies, and as a result, A&M was not only undefeated for the third time ever, but also earned national championship recognition for the first time.

Admittedly, the early season schedule wasn’t difficult. Texas A&M beat non-major programs Sam Houston State, Texas State, Howard Payne and Trinity by a combined 159-0 the during the first five weeks of the season. But, head coach Dana Bible’s squad also played rivals SMU, TCU, Baylor, Texas and others. When the dust settled, the Aggies blasted their 10 opponents by a combined 275-0.

1. 1939: 11-0, (6-0) Southwest Conference Champions, National Champions

The last Texas A&M football team to win a national championship, the 1939 Aggies also featured one of the best defenses in school history. Led by head coach Homer Norton, Texas A&M allowed just 18 total points during the regular season and held each opponent to seven points of fewer. The Aggies also recorded six shutouts and finished fourth nationally with 2.8 points allowed per game.

After a 10-0 regular season, Texas A&M secured the No. 1 ranking in AP poll, and earned the first Sugar Bowl birth in school history. The Aggies defeated SEC champion Tulane 14-13 in come-from-behind fashion to cap the perfect season.

In the first of two consensus All-American seasons, running back John Kimbrough led the Aggies with 634 rushing yards and scored 11 touchdowns on the ground. Kimbrough also added a TD reception for the A&M offense, which ranked No. 18 in the country with an average of 19.3 points per game.

In 2014, the Aggies wore beautiful ’39 throwback uniforms to celebrate the greatest Texas A&M football team of all-time.
