You're thinking Double Wing. The qb was called The Spinner in the Double Wing. He would spin the opposite way from the hole the running back was going thru . The Fullback was called The Sniffer as he was lined up just behind The Spinner's butt. Like a yard behind. As an OC we used the Double Wing in bantam football here in Calgary. The Ol had no splits. It was just push ahead for the Hoggies & the back find the hole. In the Wedge, all the linemen aim for the same DL pushing him back about 15 yards. It was an offense from the 1920's but man, did it work! Only problem was leakage as DL could come around the Wedge & tackle the RB from behind. Only problem for the defense was by the time someone did we already got the first down.
I switched to that offense mid season as we had a qb who could make all the throws but only one receiver who could catch. Our kids dropped so many catchable balls & we left TDs on the field every game. And we were 1-3 going nowhere including being shut out twice in 4 games. After a 15-0 loss to a bantam team we should have defeated, frustrated I went home, stayed up all night & brought in a Double Wing offense. Our OL loved it, our backs loved it, our qb loved it as he got to do a bootleg behind The Wedge & block downfield which he also loved. Our receivers loved it as they didn't have to catch anymore so the pressure was off & all they did was block. We went from a running attack of less than 50 yards a game to almost 300 yards a game. We won some ball games last half of the season & actually made the playoffs. Every defense hated playing us because we were such a physical offense.
