Just killed some time and compared all of these teams. Harmony's losses are not like the others. The only team remaining in the playoffs to beat them is Beckville a 2A team. Aledo's 2 losses came to Guyer who is in the Semi's and Paris Epis.(sp?) who won State. Brock's losses have 3 teams still in the playoffs in Pleasant Grove, Wimberly, & Gunter. The other was WF Hirschi, who should have done better. SOC's has 2 teams still in the playoffs of their 3 losses in Duncanville and Desoto. Lancaster was a mighty foe as well. Decatur only has one as well in Anna with the two losses to Stephenville and WF Rider.
With all that being said, everyone but Harmony(no offense) came out battle tested and ready for a run. Doesn't shock me they are doing well in the playoffs.
