And, Jazzo - I was actually taught how to run a flag team by someone else with a lot of experience, so I never considered myself even close to being good enough for coaching tackle.
Won 3 city championships with 12 and under teams though.
When I was taught the polecat, I was taught it with the swinging gate (extra point formation). I asked why don't you see this formation in the pros (ya know, just to throw things off). Dude was like, "Nah, at their level of play, they'd eat this play up all day.'
Just one of those things that exploits the huge talent gaps that exist among kids.
