No I meant that instead of feeling nervous even before the match, Novak would have felt confident and thrilled to play Rafa because he would have been sure that he was about to win Wimbledon. And that would have make him play better.
For your previous comment :
I chose this specific match because it is an extreme example to show my point of view better, maybe that was counterproductive. Basically I wanted to say that judging a player's level on a day to predict an other hypothetical (just like the other topic Rafa 08/Novak15) doesn't work because everything is influenced by what happened before the match (even every point during a match is influenced by the previous points).
And the player who shows the better level is not even necessarily the one who wins (you could use the example of the level of the 2 finalists of W19 to say that Roger wins the same hypothetical, which is conceivable but of course it didn't happen). Which leads me to say that I expect Djokovic to win most hypotheticals peak for peak against Roger in slam finals, just because of mental superiority, it doesn't matter to me that Roger shows a better level to decide who I expect to win).
As for Djokovic, having lost in 2014 against Stan makes me think that considering that his physical abilites were perfectly fine at the start of 2015, he would have raised his level as much as needed to win against anybody, just like Nadal did in RG17. Maybe that's what happened to Roger in AO07 too.
