A Roger Federer win would only mean:
- A 7th Wimbledon title tying Pete Sampras’ 7
- A record extending 17th Grand Slam singles title
- A return to the #1 ranking
- Tying & surpassing Pete Sampras for the most total weeks at #1
- At 30 years of age this could possibly be a final major title and a final trip to #1 for Federer
With all of that at stake for Roger, there is much more is riding on Murray’s performance. I am not sure what that means for the final as this level of expectation is essentially uncharted waters. Imagine that you were playing in the final of the most important event in tennis on home soil when your home country popularized and spread tennis around the world. Imagine all of that being coupled with a massive title drought. It is more external pressure facing a player than has ever been placed on a player.
Internal pressure is something one cannot measure. Maybe all of the external pressure leads to an inner calm for Murray. Maybe it crushes him like a grape being stepped on by an elephant. Roger, largely due to age, has a lot of internal pressure regarding this being perhaps last great opportunity of his career. I can see Roger winning another major or two even if he loses Sunday, but the top ranking is not likely to be this close again. This is a psychologically epic match. I just hope that the quality of play is not crushed by these conditions.

Would Roger be guaranteed more than one week at #1 with a win Sunday?
Yes, in that no one will be playing Newport to try to grab 250 ranking points. Fed would likely hold the ranking at least through the Olympics if he wins Sunday.
