The defender that the guard blocks should never be right, both because the guard has freedom to push him wherever, and the runner’s job is to cut off his block to make him correct - the runner cannot just guess.
If it all works well, the line should have crushed anyone to the inside of the offensive guard, while the fullback has kicked out the end man on the line, and the pulling guard is the runningback’s personal protector. It is a power play so he has to be willing to hit the hole fast it’s not as much of a “read the defense” run as are zone runs, though it is a good complement to it. As stated above, he wants to cut off that man’s block and get vertical quickly. The runner takes a lateral or slight delay step, takes the handoff from the quarterback, and follow’s the pulling guard’s block. He can block him whatever direction is best it’s the runningback’s job to find the open lane.
He pulls and “leads,” meaning he retreats, looks first for the fullback’s block to cut off of, and then heads into the crease looking to block the first defender that shows up - typically the playside linebacker.
The final piece of the puzzle is the backside guard (sometimes nowadays a tackle). He uses a “kick out” technique, simply meaning he blocks him from the inside to out, in order to create Lombardi’s famous “seal” going the other way. First, the fullback (or, more often nowadays, some kind of H-back or other player) is responsible for blocking the otherwise unblocked end man on the line of scrimmage (“EMLOS”). They can do this because they get some help to the playside. To use Vince Lombardi’s phrase, the idea is to get so much force going that direction that they completely seal off the backside. For the guards and center, that includes anyone “heads up” or covering them, but for the playside tackle, he does not want to block the defensive end or other “end man on the line of scrimmage.” These lineman use their leverage to get good angles to crush the defensive lineman, and the fact that they don’t have to block a couple of defenders on the playside frees them to get good double teams and block the backside linebackers. The lineman to the side the run is going (playside) essentially “down” block, meaning they take the man to the inside of them.
