The success of any great match or pay-per-view hinges on the collective performance of the Superstars and Divas involved.
But that does not mean that single performances are unimportant.
A Superstar's individual showing can determine their long-term future with the company. It can determine who will rise up the card, who will stay in the spots they currently inhabit and who will plummet down the card, their performance far more disappointing and detrimental to their careers that anyone could have imagined.
Luckily enough, SummerSlam was an outstanding show devoid of any real negative performances. Each man and woman involved worked hard and it was clear in the quality of the overall show and the individual matches.
