By the end of this article you should be able to make an educated guess
as to what Braden is saying to A.J. Williams [Fuller]
You may have heard Michigan has a new offensive identity, by which of course we mean Michigan now has an offensive identity. We think. We're told. Evidence for this is Michigan hired a new OC who runs inside zone, and he has even Brady Hoke talking about it being our base thing. This thing is totally happening. I mean if they hadn't sworn up and down for three years that Power was going to be their thi...
Let's just not go into that and focus on inside zone and how to watch inside zone, and how to be correctly disappointed with the correct person when inside zone isn't run very well. Since this is a new thing, and the offensive line are all relatively new things themselves, and the recent history of Michigan football has given you no reason to believe otherwise, and there are some really good defensive linemen Michigan has to go against this year, let's concede right now that Michigan isn't going to be running inside zone very well this season, especially early. Let's pretend like the coaches are going to stick it out anyway and let it play out.
IZ Resources: As well as the above-linked articles, I drew from Chris Brown at Smart Football, and this article that quotes Chris Brown on a Philly Eagles website. And Space Coyote wrote an entire article on IZ and some plays that stem from it in this year's HTTV; I'm sure he'll pipe in as soon as I mess something up here.

A Temperate Zone
What's inside zone? Maybe it's best to start with what it's not: man. In MANBALL, most linemen have an assigned guy to block; a lead blocker (sometimes a puller) is the only dude who has to make a tough, mid-play decision, and the running back just has to follow that guy.
Inside zone is a base running play where all the blockers are reacting to the defense, not just a lead guy, and the running back has to choose from among various holes that could open up. It takes a different set of skills, mastery of a different set of blocks, and most of all: reps reps and more reps so that everybody can make split-second decisions and those decisions will be correct.
That's not to say all decisions are made after the snap. In fact most blocking assignments are determined by how the defense is lined up. In many cases it won't be all that discernible from man-blocking.

The read OL have to make is whether they're "covered" or not. Covered means there's a DL lined up across from you. If there isn't, you are "uncovered" and most likely you'll get to go hunting linebackers. But first you look next to you and see if there's a defender shaded to the playside of your buddy; he may need help with that lineman before you release downfield. If that defender is a beast your buddy may need all the help he can get. You deal with the first level defenders before you worry about stopping linebackers.
Almost always, more than one defender will arrive in a blocker's zone. So zone blocking means lots of shared blocking. Ultimately the blocking ends up being 2-on-2 instead of 1-on-1. For example in captioned illustration above-right, the center and right guard are together responsible for blocking the nose tackle and the middle linebacker.
Offensive linemen in high school seldom get the right footwork down. Zone-blocking footwork isn't the same as pile-driving some dude, for one; and two it's not something many high school coaches know how to teach; and three if you're a 6'6"/300 future Big Ten OL and your job is to block a 6'0"/180 future Big Ten economics major, your greatest motivation to pay attention to your feet is probably the preservation of your prom date's.
In this moment it matters greatly. You need to get off the snap, get playside of your defender, get downfield, and get your feet set beneath you, your hands inside, and your pads beneath his so you can ride him out of the play, stonewall him, or shove him downfield; you let him dictate his fate.
On inside zone, an uncovered guy's first step is always to the play-side, not directly toward the guy you're going to block (the OL taking this step is a good indicator it's a zone-blocked rather than man-blocked play). This is because the DL don't always come straight upfield; you don't want them running by you.
Your job is to block the guy trying to cross you. If someone lined up inside you and ran further inside you, he's not yours. Your head stays downfield until you lock on a target, and any object that attempts to cross your field of vision must be stopped.
That Rabbit's Dynamite
Interesting example of a 1) a cutback and 2) the U starting on the strongside of the formation then executing his backside block almost like a lead blocker
Mastering the combo blocks and footwork to respond to all the things defenses throw at you takes a bazillion reps. The upside: inside zone, like option offenses, is a multi-attack threat that can go where the defense doesn't. A called IZ play could end up going outside, or inside, or cut to the backside depending on how your opponent defends it. A well-run IZ offense doesn't let defensive fronts play aggressively; if they want to stop you they'll have to activate the safeties in the run game, opening up the pass. It's not wimpy; it's smashmouth football that—as you'll see—relies mostly on crushing blocks to break things big.
[After the jump I'll show some sample executions versus various defensive alignments so you can get a sense of how it attacks and what factors lead to its success.]
