these were 1A schools in Texas. That classification was just changed so that football and all the other sports would be in an actual class. Previously it was called something else (can't remember) because they play 6-man football.

It WAS 1A, and still is. Has been since 1980 when they eliminated Class B and went from 1-5A. Starting with the 2014-15 season, they added a 6A. What they did do, and what I think you're talking about, is that there is no more 1A 11-man football. All 1A schools play 6 man football (or perhaps don't play football). I'm sure there was some reorganization with small schools that played 11 man football and used to be in 1A, but other than moving schools around, that didn't affect basketball.

Previously, schools that played 11-man football and 6-man football might have been in the same 1A district for basketball and other sports.
