Good story, but you need to make up your mind about the number. 
3,500 - 5A won 5
1900 - 4A won 2
400 - 1A won 4
Back then 1A-4A each had 8 Districts of 8 teams each. 8 Teams made the playoffs. You either won your District and moved on, or you didn't. Wasn't any of this 2nd chance bulShyte as here in Ks.
5A had 6 Districts of 6. Again, you either won and went on or your season was over. BTW, everyone played 11 regular season games.
My two favorite stories:
1. We had won our District 17 straight years and after year 7, nobody in our district would play us. Quote from the other ADs and Coaches; "You designate who you want to be your District games and we will approve them. We are not playing you any more."
Honest to god, we sometimes had games 8 hours, one way, away. We'd leave early Friday after a team breakfast and get back 3-4 Saturday morning.
2. We had black players on our team like all the teams in the city did and once in a while that caused problems. Now, remember this was the 60s. After one game, where we beat a REDNeck azzHole 4A team, as the team bus was heading to supper (by state law if any athletic event cause missing a meal, the school had to pay to feed everyone.) The team bus was being hassled by pickup trucks with "Macho Men" hollaring racist stuff and just being pains.
Again, remember this was the 60s and when a Coach said jump, the correct answer was "How High." If you had to run, you N-E-V-E-R asked how far. But as the bus pulled into the diner where we were going to eat, the team, to a man, told the Coaches they had some business to take care of and the Coaches were TOLD to go into the diner.
The Coaches actually left, asking no questions. When the team got into the diner about 15 minutes later, nobody said word one. But we never got hassled by any team we played or their people ever again.
Might be my Absolutely Proudest time as a football team member.
Last point, sorry to go on so long, but every Sunday football players from all the schools met in one of the huge parks in town and we played touch/tackle football in sweats. Honest to Gawd, I never heard one rough ridin' racist comment either year I played. As long as you were an upright-non-cheater everyone got along.
Fun note, soon to be OU QB Steve Davis and some of his friends and players we competed against would slip over from Salisaw and Muldrow and join us on Sundays. He was a couple of years younger than me but we tried to kill each other in the football games and then always had a great time at track meets. Both of us threw the shot and discus.
