Frequently Asked Questions
What is the Fantastic 50?
The Fantastic 50 is a ranking of a state's top fifty high school football teams, regardless
of classification. In North Carolina, there are nearly 400 eleven-man teams competing, and Ohio has almost twice that many.
How is the Fantastic 50 different from other polls?
Most polls are determined by the opinion of a handful of sports writers, who
can be vulnerable to regional bias and may not be able to follow every team
across the state. The Fantastic 50 is a computer ranking, similar to
those used in college football’s Bowl Championship Series, so it's
completely impartial. Also, the other current statewide polls rank teams
only within their own classification, but the Fantastic 50 is a ranking
combining all classifications.
Why have an "all-classifications" ranking?
Some people assume that even the best smaller schools couldn't compete with the top teams from large schools, but this is often not the case. The Fantastic 50 gives smaller
schools a chance to be measured against (and sometimes finish ahead of) the
large schools.
How do the 2009 rankings work? The method for the rankings is based on linear algebra; it has some similarities to the Colley Matrix
method used in the Bowl Championship series rankings. My method
includes some additional elements that Colley does not:
margin-of-victory, home vs. away games, and unequal weighting of games
(recent games count more, as do games against similarly-rated
opponents). Margin of victory (or defeat) is used, but capped at 21 points; this means that (in the rating
system) winning a game by three touchdowns is considered sufficient to
show one team's dominance over the other for that night. The results of a previous season are used as a starting point each fall. In setting up the 2009 rankings, I included (for the first time) the number of returning starters, returning key skill players (QB, top RB, and top WR), and coaching changes in off-season adjustments that influence the season-opening ratings. Just like in past years, pre-season rankings diminish in importance as the season goes on. What do you know about ranking football teams?
I was first involved in North Carolina high
school football as a statistician at Raleigh’s
Enloe High School, in the early 1990s. After studying mathematics and sports
medicine at the University of Florida, I returned to North Carolina as a math teacher and head athletic trainer at
Fuquay-Varina High School for several years. During this time, I began developing my own ranking system, which made its statewide debut in 2001 and has continued to evolve since that time. In 2008, I completed a Ph.D. in applied mathematics at N.C. State University and began a position as a math professor at the College of Wooster, in Wooster, Ohio.
How are games against
private schools and out-of-state opponents treated?
Only schools that are members of major state associations (the NCHSAA
or NCISAA in North Carolina, and the OHSAA in Ohio) or that play a substantial number of games against those teams are rated, so only games against these opponents are included.
Games against other teams (out-of-state schools and most unaffiliated
private schools) are not used for ranking purposes, as it
is difficult to judge the strength of these teams. However, beginning with the 2006 season, the results
of these games are included in the records displayed for each team. Also, for computing playoff qualifiers in Ohio, I do follow the Harbin points system, including the use of out-of-state games.
How are forfeits dealt with? Games that were forfeited and not played (for example, if a school drops the football program in mid-season) are noted in teams' records, but not used in any way in the rankings. Games forfeited after they are played (usually when the winning school finds that their team had an ineligible player) are noted as forfeits, but the original on-field results are used for ranking purposes.
How is that fair? Couldn't a team forfeit all its' games, and still be ranked? These rankings are not intended to be "fair," but instead are meant to most accurately compare the strength of all teams, predicting the results of future games. An ineligible player rarely had such a large role as to swing the outcome of a game. In many cases, the ineligible player did not even step on the field, but his presence on the sideline (dressed to play) is enough to cause a forfeit. In 2002, I took criticism for having Burlington (NC) Cummings highly ranked at the end of the regular season, after they forfeited six wins. That team slipped into the playoffs at 4-6, and went on to win the 2A state championship.
What is the significance of the rating numbers? An average team (compared with all teams in the state's major association) would have a rating of 100. Ratings of 115 are good, 130 great, 85 fair, and 70 poor. To predict the margin of a game between two teams, take the difference between their ratings, then give 1.5 points to the home team. In cases where this makes a predicted margin of more than 21, it is adjusted downward by a mathematical formula, since most teams winning by a large margin ease up as the game goes on.
Why are some NC teams' win-loss records not the same as the ones printed in
the newspaper?
For playoff seeding purposes, the NCHSAA allows teams that play 11 regular-season
games to drop the result of any one non-conference game; sometimes these
adjusted records are published in media outlets. This looks like a lot of work ... how much time does it take? Using some number-crunching software, I can run all the computations (even for playing out the season thousands of times) in just a few minutes. The work involved is in maintaining the computer code, collecting and organizing all the data (scores, schedules, etc.), and posting the results on the web site. There is a lot of set-up work involved, prior to each season's first rankings. During the season, all the substantive work for this project is done on Tuesdays, and is generally finished by early afternoon. Including answering questions from readers by e-mail, on JJHuddle, and on NCpreps, I probably spend about ten hours a week on it, four months out of the year.
Do you get paid to do this?
No ... I provide these rankings and predictions as a public service, because I enjoy both mathematics and high school football. My employer, The College of Wooster, supports my involvement in the broader community through this project. Additionally, I have sometimes have chances to talk about the mathematics behind the rankings at math conferences, as well as informally with college students and high school teachers. How much traffic does this site get?
During the 2008 season, there were over 170,000 hits (page views), including almost 9,000 on the day following the end of the NCHSAA regular season. Early in the 2009 season, daily site traffic is running at about double last year's levels. Not surprisingly, Tuesday (when I post new content) is typically the busiest day of the week. Typically, about 2/3 of the readers are looking at the Ohio content, but the NC readers (many of whom have followed my rankings for years) tend to pore the details more carefully, looking at many pages.
I have a question that's not addressed here. How can I get it answered?
