C-7 Technique

The Pro/Twins formation out of 21 personnel could become a cause for concern among Quarters coverage advocates because of possible adjustments to the tight end (or three man surface) side.  This is referred to as the "nub" side of the formation.  To the side of the twins, it’s true that many coaches will play combo coverage with the Corner and Safety to the side of the twins - this will be detailed later in the report when addressing 2x2 formations.  But, to the side of the tight end, we’ve found that some coaches will execute what they call a C-7 technique (Diagram 20) to provide run support.  Because the Free Safety is stretched to the twins side, the Corner on the backside must play a technique that requires him to play at seven yards in the C gap.  Of course, there are some negatives to this structure, particularly giving a smaller, athletic player the responsibility of playing an inside gap in the run game.
