THE ADVANTAGE DOESN'T HAVE TO LAST THE WHOLE MATCH.

Observation

A team can dominate the terms of play for a few minutes without dominating the whole game. A short period of control may be enough to change what happens next.

Try Looking At

Watch what a team does with a favourable period rather than asking whether it sustained it for ninety minutes.

Counterpoint

A short spell may simply coincide with fatigue, score effects or temporary changes in the game.

Doesn't Fit

If the advantage leaves no observable change once the spell ends, its significance may be no greater than the events that occurred within it.

Question

How long does an advantage have to last before it changes the game?
