You just can't win in this sport if you can't break serve.
It also puts your own serve under too much pressure.
Unless Rafa works hard on his fitness, his return of serve, and his backhand he won't be making any finals, let alone trying to win them.
Lack of enough hunger and desire to work on those 3 things is killing him on tennis courts.
Rafa can stop djokovic. He is the only one who can.
