There was a team a town over from where I used to coach that runs the double wing offense. They have the kids run it all through Pop Warner, middle school, and then a more complex version at the high school level.
They are 79-5 since 2015. Won 5 of 7 state championships, lost one in a huge upset and the other was to a private school that recruits players from all over the southeast. The head coach is a Hall of Famer. He's only lost 20 or so games in his career. His two losing seasons were when they have Kelly Bryant (former Clemson QB) and they tried to run an Air Raid offense. He got pissed, went back to the double wing, and Bryant transferred to a powerhouse Air Raid (that we upset in the playoffs - picked him off 4 times).
It's a badass offense.
