the game didn't rest on this decision
the idea is to be good enough to influence the game to the point where it doesn't matter what outside influences may or may not come your way
Your second sentence doesn't apply to a team like the Phoenix really. If Barcelona or Bayern Munich get one decision not go their way, sure they'll probably go on to win anyway. But a team like Phoenix any one decision will make or break whether they can get a result that week because we're not as good at putting our chances away, so if instead of 0 goals we get 1, yeah that's a massive difference that could've given us some points given how our defense has conceded less than the majority of A-League teams.
