I’ve never heard this before. It makes sense logically, but anytime I’ve heard midline referenced I think it’s been midline option.
When it comes to football terminology what its called in one playbook is going to differ.
For instance in our playbook our base set is "Spread" according to Johnson when he's talked about it. In the flexbone system i played in ( that was directly based off the johnson system at southern) we called that formation Ace. What im talking about is a terminology on how to attack the field. It is highly likely that coach johnsons calls midline he's referencing the option. But seeing as longest and guys like alex carrick on youtube are looking at this without our actual playbook I was simply saying he wasn't wrong to call something going up the center's butt a midline.
As for terminology. When we are talking about power or veer run games you typically look at runs as being one of four types based on where they attack the line. im going to break down the targets and the normal offense play and then say which plays in our offense target what.
Midline- This is an attack that attacks the center of the line (usually the 0 hole) or the midline gap. Sometimes these plays can be traditional dives or traps that use midline clearing action ( center downs on backside tackle backside guard pulls through the gap to target the mike, playside guard drives the 3 tech). Usually zone schemes do not have plays that target this gap because the gap basically becomes the playside A gap.
A gap- this is is the bread and butter inside run target in most systems. A common play ran in a non flex system that targets this zone is the Straight dive / inside zone out of the singleback used all over the place in the NFL or the I-Form Iso.
Off Guard/ B gap - This is usual the target of a stretch or belly type play It is usually ran against the shade side behind a double block on the shade. Or a backside trap.
Off Tack/C gap - This is is one that targets the tackles outside hip. When on the end of the line the concepts can extend to unbalanced ( we usually don't call that a D gap but its what it is) Outside Zone plays used by 90 percent of offenses that use zone schemes mainly run off tackle OR targeting the B gap. Inside zone is actually very rarely run outside of the NFL level ( the read is very hard on most backs and you need a certain amount of speed to do it).
Off Tight end(for us this doesn't matter but in traditional flexbones and other offenses, this is toss crack, jet sweep etc)
as for our offense. The basic principle of a veer offense or an option offense is to challenge two or more gaps per play to force defenses to guess wrong. We do this by manipulating the unblocked defenders. So at a big surface level here are some play series and what gaps they target.
"Zone Dive"- This is usually not really a zone play, we rarely actually run a zone dive, most of the time vs ODD sets we run an B gap dive, or trap sometimes even with a center pull. Against an even set we typically run this against the shade. This play is a single gap play. Sometimes against an even front if they are particularly flowing hard with twirl motion we run this on the midline, usually with a counter action, often this gets called counter-trap but the target is usually off the centers butt as he clears the shade. We have 3-4 plays that really get called this and its all based on fronts.
"Midline"- Midline is a double option that targets off the center and the A gap. Its extremely fast hitting. This is not to be confused with QB follow. These plays are usually not the ones that hit homeruns unless they don't take the b-back. Sometimes we run a very similar action that targets the A and the B gap instead. This is usually against Odd fronts or if someone has a particular stud nose that is killing our center.
Triple out of standard sets- we run so many triple concepts that are fundamentally the same play but with different targets based on formation and this is the most analyzed play we have but safe to say this usually targets the weakside (shade) B gap ( dive) the C gap (keep) and the outside (pitch). The belly triple ( not often ran but we did run it in the past) this actually targets the 3 tech B gap and the C and the outside, its usually always ran when we are having trouble sealing the the backer and we are outside releasing the tackle because they are hard slanting the outside end. 90 percent of the time this is a keep read and ends up being a double option.
QB-Follow/QB ISo- more often than not this is what makes midlines confusing. This play is actually a load ISO that targets the B gap on the weakside or a gap on the playside or either if odd front. This is a keep the entire way, it has a fake action but its always a keep and designed to run off the b-backs hip. Usually it takes on a bit of a zone feel when ran to the a gap side as its based on how the three tech plays it. if he crashed hard usually the guard washes him and the a-back goes to take the mike and the QB takes an outside line. if he jumps out the QB follows inside as the guard vertically removes him and he takes a straight line.
Zone Option- This is a new one for us, we have so far been running it out of the tight formation and it targets the C and D outside gap with a load. Unlike most options which seek to get the ball to the a-back or the b-back. this one is a QB keeps unless. Off of this play we have the QB lead sweep, now also the A-back reverse and the zone action pass.
wow this got long. And agian remember this is the terminology I know. I tried to map our common names to what i know.
