Since Michigan’s offense will call the zone-read option its bread-and-butter play for the next few years, fans are probably interested in how the play works. Slightly more interesting than “run left,” I assure you.
Most important to the smooth operation of the zone-read is not a quarterback who is blazing fast, but a signal caller who can make the right decision with the ball, and can at least do a little damage with his feet.
The play operates out of the shotgun, with either one back to the QB’s side or one split to either side of him. The running back for whom the play is called will start lined up on what will eventually be the backside of the play, since he crosses in front of the quarterback (this is not always the case in RR’s offense, but for the sake of the basic play, we will start with that). The offensive line will block down to the playside, leaving the backside defensive end unblocked. This is the player that the QB will read (hence the name “zone-read”).
The quarterback takes the snap, and the running back crosses in front of him. The QB puts the ball in his stomach, but does not hand it off. This is called the “mesh point” where either the QB or the running back can end up with the ball. It is at this point that the quarterback must be able to make a good decision with the ball, and read the defensive end. If the defensive end stays at home and holds contain, the quarterback simply hands off the ball to the RB. The offensive line is expected to outnumber the defenders, and block everyone for a good gain (or excellent depending on execution and the running back’s vision).
If the defensive end gets greedy, and decides to try to chase down the running back from behind, the quarterback pulls the ball out from the mesh point, and runs back past the end, and gets a decent gain (if the offensive line blocks well, the QB should be able to get to the second level without facing a defender). The quarterback makes this read if the defensive end turns his shoulders toward the running back, rather than keeping them parallel with the line of scrimmage, as he would if keeping contain.
For those who are visually oriented:
This is obviously the very basic play, so there are lots of other variations on it. For example, backs can be motioned into or out of the backfield, slot receivers can be used as pitchmen, the play can be designed to go towards the direction that the RB is lined up, rather than the opposite direction, etc. The option-pass can also be effective, with the play run the exact same way, but if the DE crashes, the quarterback, instead of trying to gain yards, rolls out for a pass, using the zone-read as a play-action.
If my explanation was confusing (and I hope it wasn’t), have Rodriguez explain it to you himself:
