Determining the greatest college football teams of the last century requires balancing statistical dominance, championship hardware, and the era-specific challenges of the sport. According to CBS Sports, the selection process highlights programs that defined their respective eras, ranging from the legendary 1945 Army squad to the modern-day dynasty of the 2020 Alabama Crimson Tide.
## Defining the Greatest Teams by Decade
To identify the premier team for each decade since the 1920s, analysts at CBS Sports utilized a combination of national title wins, undefeated records, and strength of schedule. While modern recruiting and conference expansion have shifted the landscape, these selections represent the programs that maintained the highest levels of sustained excellence during their respective tenures.
| Decade | Team | Key Achievement |
| :— | :— | :— |
| 1920s | 1924 Notre Dame | 10-0 record, national championship |
| 1930s | 1935 SMU | 12-1 record, Rose Bowl appearance |
| 1940s | 1945 Army | 9-0 record, national championship |
| 1950s | 1956 Oklahoma | 10-0 record, national championship |
| 1960s | 1961 Alabama | 11-0 record, national championship |
| 1970s | 1971 Nebraska | 13-0 record, national championship |
| 1980s | 1987 Miami | 12-0 record, national championship |
| 1990s | 1995 Nebraska | 12-0 record, national championship |
| 2000s | 2001 Miami | 12-0 record, national championship |
| 2010s | 2018 Clemson | 15-0 record, national championship |
| 2020s | 2020 Alabama | 13-0 record, national championship |
## Why These Programs Dominated Their Eras
The criteria for these selections emphasize dominance over parity. For instance, the 1945 Army team, led by Heisman Trophy winners Doc Blanchard and Glenn Davis, is frequently cited by historians for its overwhelming scoring margin. Similarly, the 2001 Miami Hurricanes remain a benchmark for modern talent, featuring an unprecedented number of future NFL draft picks on a single roster.
Comparing the 1995 Nebraska Cornhuskers to the 2018 Clemson Tigers reveals the evolution of the sport. While Nebraska’s “Option” offense relied on physical dominance and ball control, Clemson’s 2018 title run—the first 15-0 season in the modern era—demonstrated the shift toward high-tempo, pass-heavy offensive schemes.
## Contextualizing Historical Success
It is important to note that these rankings reflect the state of the game at the time. Before the Bowl Championship Series (BCS) or the College Football Playoff (CFP) era, national champions were often determined by wire-service polls. Programs like the 1935 SMU Mustangs were selected based on their regional influence and impact on the national rankings during a time when bowl games were less centralized.
The inclusion of the 2020 Alabama team serves as a bookend to this century-long analysis. Despite playing a conference-only schedule due to the COVID-19 pandemic, the team’s offensive efficiency ratings remain among the highest in the history of the sport, according to advanced metrics tracked by national outlets.
## What Defines a “Great” Team?
The debate over the greatest team often hinges on whether one prioritizes a single-season peak or a multi-year dynasty. While CBS Sports focused on the single best team from each decade, the programs that appeared most frequently—specifically Alabama and Nebraska—demonstrate that consistency is the primary driver of historical prestige in college football. As the sport moves into a new era of expanded playoffs and conference realignment, these historical benchmarks provide the standard against which future champions will be measured.
