2025 cfb season qb advanced stats preview

CFBNumbers cuts through the noise of preseason hype by admitting a hard truth: ranking college quarterbacks is a statistical nightmare because the gap between a "death machine" defense in Georgia and a FCS opponent is too wide to ignore. Rather than offering a gut-feeling list, the author builds a custom linear mixed-effect model to isolate individual quarterback value from team performance, a method that surprisingly demotes highly touted freshmen in favor of seasoned veterans.

The Problem with Traditional Metrics

The piece begins by dismantling the idea that raw stats tell the whole story. CFBNumbers writes, "There is much debate on how to judge Quarterback performances with numbers, as it is extremely hard to separate their individual abilities from the team around them." This is the foundational premise that elevates the analysis above standard box-score recaps. By acknowledging that a quarterback's efficiency is often a product of the offensive line and the quality of the opponent, the author sets the stage for a more nuanced evaluation.

The author introduces two key metrics: Expected Points Added (EPA) and Completion Percentage Over Expectation (CPOE). The goal, as CFBNumbers puts it, is to find the players "able to complete passes adjusted primarily for distance... and is overall efficient on their passes and rushes." This approach highlights Duke transfer Darian Mensah as a standout, noting that he "takes the crown for EPA/Play + CPOE." This is a bold claim for a transfer, suggesting that his impact will be immediate and measurable regardless of the system he enters.

However, a counterargument worth considering is that these advanced metrics, while sophisticated, still rely on historical data that may not account for sudden scheme changes or coaching adjustments in the upcoming season. A player's past efficiency doesn't guarantee future success if the supporting cast collapses.

Building a Custom Model for 2025

To solve the limitations of existing stats, CFBNumbers constructs a proprietary model designed to answer a single, critical question: "How many points does this QB add to their team?" The author explains the methodology, stating, "I built myself a linear mixed effect model that attempts to predict how many points a QB adds to his team." By treating the quarterback and the opponent as random effects, the model attempts to strip away the noise of varying defensive strengths and isolate the quarterback's true contribution.

The results of this model challenge conventional wisdom regarding the hierarchy of talent. While names like Arch Manning and Dylan Raiola dominate social media hype, the data shows they rank lower due to a lack of sample size. CFBNumbers notes, "Arch Manning didn't even make the graph above because he has less than 100 passes and rushes in his young career." This is a crucial distinction; the model is descriptive of what has happened, not predictive of what might happen. It favors experience, placing established players like Carson Beck at the top.

"We can also look at a QBs point rating and what their 247 composite high school recruit rating was when they were coming into college."

The author uses this data to highlight the value of under-recruited players who have outperformed their initial projections, such as Jalon Daniels and Parker Navarro. This reframes the narrative from "who was the best recruit" to "who has actually delivered value." Critics might note that this heavy weighting on past performance could penalize young talents who are on the verge of a breakout, potentially causing fans to overlook the next star until it is too late.

Conference Strengths and Draft Implications

The analysis shifts to a conference-by-conference breakdown, revealing that the Big 12 leads with ten of the top thirty quarterbacks. CFBNumbers observes, "While the Big 12 and ACC have some proven QB talents, I would argue the Big Ten and SEC have more talents we hope will step up this season." This suggests a potential shift in the power dynamic where unproven talent in major conferences could outperform the established stars in others.

The piece also touches on the correlation between this custom model and Pro Football Focus (PFF) metrics. The author finds that their model "appears to favor QBs with more rushing abilities," whereas PFF captures more of the volume of snaps. This distinction is vital for understanding why certain dual-threat quarterbacks might rank higher in this analysis than in traditional scouting reports.

In the final section, the author offers personal NFL draft rankings, admitting that their gut feeling sometimes diverges from the data. CFBNumbers writes, "I am also higher on Aidan Chiles than the point rating system is, as I believe he has a chance to put everything together with one final year." This admission of human intuition alongside algorithmic rigor adds a layer of credibility, showing that the author understands the limits of data.

Bottom Line

The strongest part of this argument is the transparent methodology that prioritizes experience and isolates individual impact, effectively neutralizing the bias toward high-profile freshmen. Its biggest vulnerability is the inherent risk of relying on past performance to predict a volatile season where coaching changes and injuries can upend even the most robust statistical models. Readers should watch to see if the "proven" veterans hold their ground or if the data's skepticism toward the new generation proves wrong in real-time.

IT IS TIMEEEEEEEEE!

The 2025 College Football Season is just around the corner as we are officially in the preseason. I hope you all had a fantastic summer and are ready to dive into this brand new season. Before we get to overall team previews, I want to look at the most important position on the field, the Quarterback.

There is much debate on how to judge Quarterback performances with numbers, as it is extremely hard to separate their individual abilities from the team around them. Add in the fact that the opponents in college football can be everything from a death machine in Georgia to a FCS opponent, and you get a really hard task in ranking the nations QBs.

We’re going to try and do just that in this article, as well as look at some other numbers from the returning and potentially new starters in the CFB world (QB battles are going on at the time of this writing, so if I have someone on here that lost their QB battle I apologize for jinxing them).

Expected Points Added and Completion Pct Over Expectation.

I wanted to start off looking at Expected Points Added Play play and Completion Percentage over Expectation (CPOE) as just a general overview of the potential 2025 starters. The goal is always to be top right in these graphs, where in this instance it means the QB is able to complete passes adjusted primarily for distance (X-axis) and is overall efficient on their passes and rushes (Y-Axis).

While is sample size was on the smaller side, Demond Williams Jr. flashed his potential for Washington last season. His 78.1% completion percentage was 5 percentage points higher than any other QB in the FBS last season (min 100+ attempts). Incoming Duke transfer QB Darian Mensah takes the crown for EPA/Play + CPOE, which makes Manny Diaz portal addition all that more impressive. You’ll see later on this article, I am a big fan of what Mensah can do on the field.

QBs close to breaking school EPA record.

This is a different look at QB expected points added, this time coming from ESPN’s model that goes back all the way to the 2004 season. These are the QBs that are close to becoming their programs all time (since 2004) leader in EPA. I also included what type of season the QB needs to have via ...
