The AiNFLGM QB Compare tool gives you a side-by-side statistical breakdown of any two NFL quarterbacks, drawing on career and single-season data to help you make an informed assessment of their strengths, weaknesses, and overall tier. Evaluating quarterbacks is one of the most debated topics in football — this tool replaces opinion with numbers.
The comparison covers the metrics that matter most: passer rating, completion percentage, yards per attempt, touchdown-to-interception ratio, yards per game, and win-loss record as a starter. Each metric is normalized against the league average for that era, so you can make meaningful comparisons across different seasons and offensive schemes. A quarterback operating in a run-heavy, conservative offense should not be penalized for lower raw yardage totals if their efficiency numbers are elite.
Advanced metrics are also incorporated where data is available, including air yards, time to throw, pressure rate, and performance under pressure. These numbers reveal the quarterbacks who elevate their game in difficult situations versus those who rely on a strong supporting cast. A high passer rating behind a dominant offensive line looks very different from the same rating produced while operating under heavy pressure with a below-average supporting cast.
The tool also surfaces playoff performance data separately from regular season totals, because how a quarterback performs when the stakes are highest is often the decisive factor in historical rankings and contract negotiations. Use this tool to settle arguments, prep for fantasy football decisions, or simply explore the data on your favorite signal-callers.
The tool includes all active NFL starting quarterbacks plus a curated library of recent-era starters with sufficient games played to produce statistically meaningful comparisons. Historic quarterbacks are included where data quality meets the minimum threshold. The roster is updated after each NFL season to add newly established starters and retire players who have left the league.
Yards per attempt (YPA) and adjusted net yards per attempt (ANY/A) are the most era-neutral efficiency metrics because they normalize for game pace, offensive scheme, and scoring environment. Completion percentage has inflated significantly over the past decade due to rule changes and the shift to shorter, quicker passing games, so it should not be used in isolation when comparing older quarterbacks to modern ones.
The tool presents raw and adjusted statistical outputs. The adjusted figures factor in known context variables including offensive line grade, receiver quality ratings, and defensive quality of opponents faced during the season. This gives a more complete picture of individual performance versus system-dependent production. You can toggle between raw and adjusted views to see how significantly the supporting cast impacts the numbers.
Yes. The tool includes a toggle to switch between regular season totals, playoff totals, and a combined view. Playoff performance is weighted differently in the overall grade because sample sizes are smaller, but the data is available for any quarterback with at least three playoff starts. This makes it particularly useful for evaluating the so-called clutch factor in quarterback debates.
