Federer reset the bar for others to reach.
History is now on the side of Roger Federer. The history he made. I don't believe Djokovic, Murray or Nadal will come close to winning the number of major tournaments Federer owns, 17. So we see Federer lose in the 5th set to a player he would have mopped the floor with a few years ago but that doesn’t make him less than his accomplishments. 17 major titles and he won each of the 4 at least 1 time.
It will be another generation or more before tennis fans see anything like Roger Federer again. Long live the King.
