Thanks coach. I ran this in the latter half of this season and had a lot of success with our freshmen and JV. Oddly enough, I too didn't realize it was called duo and just called it zone. I ran it out of 10 personel, 2 by 2 or open trips. This scheme worked wonders for our run game AND pass game as it built a lot of confidence for our younger linemen. This made it simple to identify who to block. Guys just gotta know, who their double partner is, and then who is our DT and LB. If defenses don't cover a slot, we throw the bubble.
