The dust has settled on the unforgettable 2018 Texas high school football season, the 99th season of UIL-sanctioned high school football in the Lone Star State. This moment in time provides us with a unique opportunity to look back over the better part of the last decade and attempt to answer a seemingly unknowable question: what is the best high school football program in Texas?

With some data help from Jerry Forrest at PigskinPrep.com, Dave Campbell's Texas Football is proud to unveil the Texas High School Football 6-Year Program Rankings, a look at the relative strength of each UIL Texas high school football program. The goal of the project is to rank the relative strength of every program in Texas over the course of the last six seasons.

Why six seasons? A six-year sample provides a steady measure of a program as opposed to an individual squad — six years represents one-and-a-half graduation cycles, mitigating the impact of a single transcendent class of athletes. In short: good programs have great teams one or two years, but great programs have great teams spread across a larger swath of time, like six years.

The rankings are based on a formula that takes into account the following five criteria:

Games Won — The raw number of games a team won relative to the maximum number possible (96 for 11-man teams, 90 for 6-man teams); so, of the maximum number of games a team could have won, how many did it win?
Winning Percentage — Of the games a team played, how many did it win?
10-Win Seasons — Of the six seasons, how many did a team win 10 games?
State Championships — How many state titles did a team win?
State Championship Game Appearances — How many state championship games did a team play?

The criteria are set against a 100-point scale, wherein a perfect six-year run — 96-0 (or 90-0 for a six-man team) with six state championships — would result in a score of 100, and a perfectly miserable six-year run — 0-96 (or 0-90 for a six-man team) — would result in a score of zero.

This year's set of rankings reflect the 2013 through 2018 seasons; last year's rankings reflected the 2012 through 2017 seasons. Please note: a team must have played in six varsity seasons to be eligible for these rankings. So, Brock joins the rankings for the first time, since the Eagles first played varsity football in 2013, while Alvin Shadow Creek will not be in the rankings, since the Sharks first played varsity football last season.

Here are the 2018 Six-Year Program Rankings presented by Dave Campbell's Texas Football.
