A puller seals the edge defender to the inside instead of driving him out, and the runner goes around the outside. Sometimes the answer to a defender who will not be kicked out, and sometimes the plan all along.
A pulling lineman blocks the end man on the line of scrimmage inward, sealing him toward the formation and running him up the field, and the ball goes outside that block. It is the mirror of a kick out: same puller, same target, opposite direction, opposite side for the runner.
It arrives two ways. As a REACTION, when the edge defender crashes hard inside and wrong-arms the kick out, there is nothing left to kick him out of, so the puller takes him the way he is already going. As a CALL, when the offense already knows that defender will not sit still to be kicked out, so the block is designed as a log from the start and the runner is coached to the outside before the snap.
logkick out, reach block, sealWhether a log was called or reacted to is invisible on film. It is also the first thing to establish before judging the block. A puller who logged a spilling end made the right read; a puller who logged an end who would have been kicked out cost his back the inside lane. Same picture, opposite verdicts.
At youth level, ends crash inside relentlessly and often without being coached to, so the log comes up far more than its billing as the exception suggests. A play whose rules teach only the kick out has a hole in it that a crashing end will find every time.
