Union Fan, Richlands ran a single wing offense especially in short yardage and around the goal line when they had the bigger QB believe he was#12!!! Mance is a Giles guy, and didnt say they ran it against Union Alot either! And John Battle has run the Wing T also, thanks for reminding me. They ran a split back veer some too! Reed ran a single wing offense against Union almost the entire game a couple of years ago up at UVA Wise field! Don't know what game you were watching, I know they ran it the entire second half and they ran that offense about half the season I think.
I can't speak to what Richlands has run in any game outside of those against Union. I just know that those games didn't include the single wing.
And I was at the Union v Central game at UVA Wise in 2013. I was in a fold out chair on the hill above the visitor bleachers. Admittedly, I left early because of the score, but unless you can show me some game film to "help" me remember there was no single wing action then either.
And, I think, Advocate was referring to power running teams that run exclusive wing formations like Giles, Clarke, Stuarts Draft, and Wilson Memorial. Just because a team ran a handful of "wing like" plays does not make them a power running team.
