The Impact of Home Field Advantage in College Football 25
College football fans are eagerly awaiting the release of the new College Football 25 video game, and one of the most anticipated features is the implementation of a home field advantage system. Home field advantage is well studied and documented. But do some teams have a larger home field advantage than others? In order to answer that we first need to talk about what home field advantage is and what it isn’t. This article delves into the complexities of home field advantage, both in real-world college football and within the upcoming game, exploring its potential impact and the factors that influence it.
Defining Home Field Advantage
Home field advantage is the perceived benefit a team receives from playing in its own stadium. This advantage can manifest in various ways, from increased crowd noise affecting the opposing team to the comfort and familiarity the home team has with its surroundings. The top of the hardest places list is a who’s who of college football. The top 10 venues listed by EA Sports are also in the top 20 in total capacity across College Football.
I make the assumption that any HFA unique to a team should not involve any factors that involve the visiting team. I assume the difference in performance of efficiency at home vs on the road, after accounting for these other “environmental” effects to be a team’s home field advantage. The (g()) functions are splines with 2 internal knots to account for nonlinear effects of travel and elevation change. I am missing venues for some of the data, a total of 330 games out of 15618 . Using the latitude and longitude of the game’s stadium and each team’s respective home stadiums I calculate the distance traveled for each team and any effects of elevation. For the purposes of this study I will not adjust capacity differences as that can reasonably be part of the home field effect.
Quantifying the Advantage: A Statistical Perspective
Quantifying home field advantage is a complex task. Theoretically, all else being equal, teams that have a bigger home field advantage should have a bigger difference of performance at home vs on the road. That could be in winning percentage or in efficiency (points or EPA per play or drive). The problem is, in college football, nothing is equal between teams or between road and home schedules. If everything else was equal, teams with bigger HFA would be further away to the top and left of the dotted blue line and teams with smaller HFA would be below the dotted blue line. The black line represents an equal winning percentage on the road and at home.
The estimated average home field advantage for all teams from 2005 to 2023 is 0.11 points per drive for the home team. Even with 18 years of data, it is difficult to detect if a team has a stronger home field advantage than another. There are a total of 247 current unique home stadiums between FBS and FCS that I have in my dataset. If I am assessing 247 teams home stadiums in my dataset to see if they have a stronger or weaker home field advantage than the average college football team, if there is no effect I would expect 20 percent of the teams to have a posterior probability greater than 0.80 of being different than the average home field advantage (HFA). That would be about 49 teams. In fact my analysis shows that only 11 teams meet such a threshold.

Factors Influencing Home Field Advantage
Several factors can contribute to a team's home field advantage. These include:
- Crowd Noise: The roar of the home crowd can disrupt the visiting team's communication and create a more intimidating atmosphere.
- Familiarity: Home teams are more comfortable in their own stadiums, knowing the field dimensions, sidelines, and other nuances.
- Travel: Visiting teams often face travel fatigue and disruption to their routines, which can impact their performance.
- Referee Bias: Some studies suggest that referees may be subtly influenced by the home crowd, leading to more favorable calls for the home team.
Disentangling Home Field Advantage from Team Ability
Can we disentengle home team ability from a home field advantage? So is Bryant-Denney Stadium a particularly hard place to play? In short of course it is. Just look at how rarely Alabama has lost there. But there’s no evidence that it is any more difficult of a place to play than the average college football home venue after adjusting for the home team. Don’t believe me? Well in 21 neutral site games over that same time Alabama had a 95% winning percentage and even had a 84% winning percentage on the road.
It’s one thing to have a ranking of teams, but if we split our data in half would we get similar results in both datasets? Corr. (Post. Corr. (Post. Generally it is very hard to estimate if one team or stadium has a stronger home field advantage than another. That being said, there are a handful of teams that may have enough evidence of a stronger homefield advantage than what you would think. These teams are not the typical powerhouse teams with large crowds. Beyond this study, a more interesting question perhaps is if there is a statistically significant effect on false start rates by stadium beyond what you would expect with multiple testing.
One of the factors in the EA Sports rankings was the number of fans in the stands but our model doesn’t show fan attendence as correlated with the stadium specific home field advantage. It even appears that attendence is slightly negatively correlated with the specific home field advantage effects. There is an important confounder here which is team ability. Better football schools traditionally have bigger stadiums and fan support. This also brings up another point which is that this model solely measures how teams play at their home compared to the average home field advantage. For Army this could be for reasons around the strict routine of West Point or its unique offense which lends itself to play better at home than the road that have nothing to do with Michie Stadium. In order to fully disentangle a team’s typical performance on the road against the effect of the stadium they’re playing out, additional effects for a team’s road performance need to be added to estimate this.

For example, the Legion ability increases the confidence of other defensive backs when the player records an interception. However, if your player goes on a cold-streak, your mental ability goes away.
So you can see how Home field advantage works differently in EA College Football 25, thanks to the new Confidence and Composure mechanics.
