I have been watching and playing competitive tennis for many years. Roger Federer is the best player I have ever seen play. Even more so in person. Djokovic did have set points in the first two sets. The pressure got to him no question. Let us not forget he is only 20 years old. I predict he will be #1 in the world at some point. Probably when Rogers skills and body degrade some.

Nadal is the best on clay but his body will not hold up near as long because of the energy he needs to use in order to win. He already has knee and back problems at 21.
As for whether Roger is playing just well enough to win it is true to an extent for all players especially in a 5 set match. Knowing that you might possibly have to play 4 to 5 hours in one match you have to conserve energy no matter how good of condition you are in.

Pete Sampras did it all the time. He knew he could hold his own serve so he would usually cruise until it was 4 all and then he would go all out in one return game to break serve and then serve out the set. He knew that even if he got to a tie breaker he would probably win it much like Roger does now.
