How to predict a win



Vegas point spread, totals, and money line
theoretically capture all available information
under the efficient market hypothesis (EMH)
Existing literature consistently enforces EMH, though
there are some published examples of deviations
and profitable strategies within wagering markets
Within the framework of this paper, we will assume
EMH holds within college football wagering markets
and will measure the success of our developed
models relative to the baseline Vegas model
Predicting Wins with the Vegas Line

Bubble chart
illustrates the
home team’s
winning percent
by the Vegas
Line, with the
size of the
bubble based
on the number
of observations
Predicting Wins with the Vegas Line

Bar chart of home team’s winning percentage by the Vegas line
The Vegas Line model





Home Win (0,1) = b1*Line + error
This model within our data explains 29% of the
variation in wins (Pseudo R2).
The line coefficient is 0.1091, with a standard error
of 0.00437, and an Odds Ratio of 1.115
Interpretation: for each additional point a team is
favored, their odds of winning increase by 11.5%
Non-linear model shows similar results
Improving the Vegas Line model


Can it be done, or does the Vegas line incorporate all
publically available information?
To test this, we added several variables:
 Home,
Away win and losing streaks
 Home, Away AP Rankings, Top 25 matchups
 Dummy variables for conference games, neutral field
matchups, and night games
 Distance between schools, stadium size, rivalry information
 Conference dummy variables

• Table on left shows these
additional variables and a their
corresponding Wald Chi2 statistics
• The Vegas line successfully
incorporates all available
information.
• Adding more explanatory
variables does not improve the
model’s fit.
• None of the added variables are
statistically significant as their
importance is already captured in
the Line variable.
Data Sources

To develop a model of winning without utilizing the
Vegas line, the authors gathered data on the
following topics:
 Game-specific
factors
 Institutional factors/history
 Team player composition/recruiting
 Team coach factors/history

We will discuss the collection and organization of
this data next
Game-specific Factors




Matchup data comes from Covers.com
Data includes game location, time, day, conference
information
Each matchup (home vs away) is one observation in
the dataset
There are about 500 games per season
Institutional Factors & History



Historical team performance comes from
CFBDatawarehouse.com
University football team expenditure and student
body size data come from the Equity in Athletics
website
Each of these variables is reported for a particular
year (e.g., Michigan’s historical team performance
through 2007 and their team expenditure data for
the 2008 season would all be used as predictors
for the 2008 season matchups)
Team player composition and recruiting



Class recruiting data comes from Rivals.com,
Scouts.com, and Prepstar.com
Recruiting classes in 2005 (RS-Senior), 2006 (Senior
/ RS-Junior), 2007 (Junior, RS-Sophomore), 2008
(Sophomore, RS-Freshman), an 2009 (Freshman) are
used as predictors for the 2009 season matchups.
Due to the NFL draft, transfers, and general
attrition, these variables are imperfect measures of
the talent comprising a team in a particular season
Team coach factors and history



Historical coach performance comes from
CFBDatawarehouse.com
Coach biographical information comes from various
university athletics department websites
Each of these variables is reported for a particular
year (e.g., Michigan’s coach’s historical performance
through 2007 would be used as a predictor for the
2008 season matchups)

Matchup-specific variables:
• Stadium Size
• Home team student size
School-specific variables:
• Cumulative Team Win Pct Diff
• Log Diff of Total Team expenditures
Team-specific variables (Difference home – away):
• Scouts.com weighted average class ranking
Coach-specific variables (Difference home –
away) :
• First year head coach Home team dummy
• First year head coach Away team dummy
• Coach age
• Coach experience (assistant + HC)
• Head coach seasons
• Lifetime Coach Win Pct Diff
• Years as NFL player
• Home team’s head coach minority dummy
• Away team’s head coach minority dummy
Initial Model - Interpretations
Matchup-specific variables:
• Stadium Size – for every additional 10,000 seats, the home team is 4% more likely to win
• (also considered game time, location, rivalry variables)
School-specific variables:
• Log Diff of Total Team expenditures – the odds ratio of the % difference (home/away) in team spending of 2.5 suggests
that a team spending 100% more (twice as much) is 150% more likely to win, (Alternative, equivalent interpretation: odds
of winning increase 15% for each 10% increase in excess of your opponent’s expenditures)
Team-specific variables (all Difference home – away) :
• Scouts.com average class ranking – for each unit increase in average class ranking between the home and away, the
home team is 1% more likely to win
Coach-specific variables (all Difference home – away) :
• First year head coach dummy variables – marginally significant and coefficients in the direction one would expect
• Diff in HC’s ages – for each additional year in age difference b/w the Home and Away team’s coach, the home team is
1% less likely to win
• Diff in HC’s cumulative Win % – for each 1% difference in lifetime win percentage between the home team’s HC and
the away team’s HC, the home team is about 6% more likely to win
• Years as NFL player – for each additional year of NFL playing experience between the home team’s HC and the away
team’s HC, the home team is about 4% less likely to win
• Home team Head Coach Minority – minority coaches are 42% less likely to win than non-minority coaches at home
• Away team Head Coach Minority – home teams are 87% more likely to win when playing against a minority coach

Practical Applications

Predict 2010 season results – conference standings,
national champion, before a single game has been
played
Next steps

What can be added to the model?
 New sources of data (attendance,
compensation/bonus – impute missing values based
on relative rank of team within conference?)
 Additional data cleanup (game time, more years
2001-2003)
 Different estimation methodologies

Are the coefficients robust?
Future problems: things that recruits like – new
stadiums, new weight rooms, facilities
Could we do a recruiting paper modeled on NCAA
football recruiting info – coach history, academic
prestige, location, tv time, etc

To begin, we will look at each of these data sources
and its relationship to our outcome variable
individually.
Because each of these data sources is described with
dozens of potential variables, this initial modeling will
inform our final set of models where data from all
possible sources are considered in development.
All models are developed using a Logit function as our
outcome variable, Home Win, is binary. We will
discuss the resulting coefficients as Odds Ratios to aid
interpretation.
