I was just feeling a bit bored this evening from neverending data entry so decided to take a break and compile some completely arbitrary stats.
20 years is being used very simply because I haven't completed entering all the data for the lowest classifications prior to 1987 but I should have the complete set of records compiled pretty soon.

All of the following stats were derived using the on-the-field results of every UIL 11-man football playoff game 1A thru 5A played from 1987-2006.

Current 3A programs are listed in GREEN
