The impetus for goal-scoring sparked in the summertime of 1925 with a revision to Legislation 11 within the Legal guidelines of the Recreation: the offside rule. Previous to that, there all the time needed to be three defenders between the attacker and the purpose when the ball was performed to them. 

This regulation was ruthlessly exploited by defenders after the First World Warfare; most notably, Invoice McCracken, a Northern Irish full-back with Newcastle, perfected an offside lure that snared forwards like an internet catching flies.
