And unlike other low scoring sports such as hockey, the away goals rule introduces the possibility of going from winning the tie to losing the tie on just one kick.I think soccer/football is most prone to the gut-punch phenomenon just because scoring is so infrequent. Basketball shots and football passes happen all the time, but a goal at any particular moment is an improbable event, especially with stoppage time elapsed and the ref looking at his watch. You'd expect to win 990 out of 1000 of those.
