Football Minds: Xs and Os Question

Is correct. A Belly run is essentially an ISO run but, someone just wanted to tag it a belly run. The main thing/objective is to send one back through one hole and another back through another to force the defense to make a decision. That's it, nothing too complicated. A good example would be the belly option where the qb would fake a dive to the fullback and run the option attacking the defensive end.

Belly - noun: another football term that has come to mean different things namely an option play or an inside zone play; in Vince Lombardi’s Green Bay Packer offense, it was a fake fullback dive right, halfback dive left with the halfback taking a jab step to the right before running to the left A or B gap bubble depending upon the movement of the defensive tackle; the left guard was to use Lombardi’s whichever-way-he-wants-to-go blocking technique on the defensive tackle and the halfback ball carrier was to read that block and “run to daylight;” verb: to run a path that goes slightly backward and away from the line of scrimmage before coming back toward the line of scrimmage as in a swing pass route

Iso - short for isolation play, same as lead play

Lead - offensive play in which a fullback goes through a bubble to block a linebacker followed by a ball carrier

The above posters are correct.

But in addition, I've been a part of one offense before (a Wing T offense) in which the tackle and guard cross-blocked.  In other words, the tackle goes first and blocks down on the defensive tackle.  The guard waits for the tackle to cross his path and then blocks out on the defensive end.  After they cross, the dive back leads through the hole on the linebacker.  Meanwhile, the fullback takes the path described above and follows the dive back through the hole.
