OIL BLOCKING meaning acronym for a mythological blocking rule; the letters stand for “on, inside, linebacker” and supposedly tell an offensive lineman to block the man on him and if there is no man on him to block the first defensive lineman to his inside and if there is no defensive lineman to his inside to block the first linebacker to his inside; obviously, the words “on” and “inside” must be defined more precisely; likely definitions would be that “on” means a defensive lineman whose nose is aligned from your nose to your inside shoulder and “inside” means a defensive lineman whose nose is in the gap to your inside or on the outside shoulder of the teammate to your inside; this rule is widely used by youth coaches who have never thought it through; it allows for no pulling and trapping; it permits no double-team blocking; it allows no cross or fold blocks; it allows no base blocking to the outside for dive or lead plays that attack a bubble; it is useless for the center who, by definition, has no “inside;” it does not work if more than one defender align in an area that is one offensive player’s “on” or “inside” area; it has all offensive linemen blocking in an inside direction which makes you wonder who’s blocking defenders who align outside the nose of the EMLOS; it is too predictable; it is susceptible to slanting by defensive linemen through the wake of the offensive linemen who are themselves all slanting inside; it probably only makes sense for playside guards and tackles in a power off-tackle play featuring a kick-out block by a fullback or a counter play featuring a pulling guard from the backside; this rule could generally only be used by playside guards and tackles and then only for some plays going to a B or C gap and only against some defenses; it is absurd to do, as many youth coaching staffs do, and use OIL as their sole blocking scheme for all positions on all plays against all defenses
