Of the district champions ... San Marcos Hill Country and Lake Jackson Brazosport had the toughest schedules. (I take the sum of a team's opponent's records and subtract the reverse of the team's record to get their opponent's W-L record against other teams.)
Lubbock Christ The King Cathedral (District 1-1) - 33-51 minus 0-9 = 33-42 (.440)
Waco Valor Prep (District 2-1) - 38-49 minus 0-9 = 38-40 (.487)
Greenville Christian (District 3-1) - 42-50 minus 3-7 = 39-43 (.488)
San Marcos Hill Country Christian (District 4-1) - 45-41 minus 2-8 = 43-33 (.566)
Spring Founders Christian School (District 5-1) - 29-52 minus 0-9 = 29-43 (.403)
Lake Jackson Brazosport Christian School (District 6-1) - 45-40 minus 3-6 = 42-34 (.553)
