"Level Is Onside"

Before 1990, an attacker who was exactly level with the second-last defender — not ahead, not behind, but level — was judged offside. Combined with an era of deep, disciplined defensive lines, it produced a version of football that was hard to watch. The 1990 World Cup in Italy delivered the lowest goals-per-game average in the tournament's history, and the finger of blame pointed squarely at defenses squeezing every marginal advantage out of the offside law.

IFAB's response, proposed by the Scottish FA, was simple: level is now onside. An attacker needs to be behind the second-last defender to be judged offside — not merely level. The stated goal was explicit: give the attacking player the benefit of the doubt, and make the game more fluid. Goals went up. The sport, by most accounts, got better to watch.

It is worth sitting with the parallel here. Decades before VAR turned offside into frame-by-frame anatomical measurement, IFAB already understood that offside's purpose was to stop unfair advantage — not to punish marginal positioning. The 1990 change moved the tolerance in the attacker's favor for exactly that reason. It is the direct ancestor of the daylight-offside argument being tested today: get the purpose of the law right, and the measurement question becomes much easier to answer.
