Tiebreaker? Help a newbie out

In this scenario of a 3 way tie head to head will only matter if district points are tied. If district points are all tied then the 3 teams will do a coin flip. The latter more than likely won’t happen because Mcalester just lost by 15+ to Coweta and the most district points they can get up to the remainder of the season is 61. In this scenario of a 3 way tie Mcalester has pretty much guaranteed 3rd considering they are already 28 district points behind Del City and 44 behind Coweta. It will more than likely stay that way to until Del city and Coweta play each other. Del City I’m pretty sure needs to beat Coweta by 8 or more points to hold the tie breaker over Coweta because both should beat the rest of there opponents by at least 15 points. Which is the max points you can get in a district win. If Del City loses they will finish in 3rd and Mcalester 2nd. If Del City wins but the don’t win by 8 or more they will more than likely end up 2nd because Coweta should still finish with more district points than them. The best scenario for Del city to win the district is to beat Coweta by at least 8 points. Both teams should have 59 and 75 district points by the time they play each other because I think both should beat there next 2 opponents by 15+ points. If Del city wins by 8 both would be tied with 67 district points with one game remaining which they both should win by 15+ points as well. That would bring both teams district points total to 82 points and Mcalester would have no more than 61 points. If that happens it would come down to a head to head tie breaker between Del City and Coweta and Del city would get the district crown.
