Granted, we don't know the details of their medical conditions, but any chronic injury to a limb is potentially career-ending in tennis. A long-term sore arm or elbow that forces a player to quit in the most important tournament of the year is pretty obviously a time bomb. The same is true of an apparent hip problem that reduces a defending champion's mobility to the point that he is double-breadsticked by a man ranked 25 places below him.
Players who have passed age 30 shouldn't bother with the typical "take six weeks off; maybe skip one tournament; claim it feels better; come back too soon; then have a repeat flare-up after two months" half-hearted approach to healing. What these wounded warriors need is a genuine, and long, off-season. It's not the Federer strategy or the Nadal strategy; it's the smart strategy.
In addition, Djokovic is obviously suffering from psychological burnout, and with another child on the way, he clearly is in dire need of down time. Murray, too, seems exhausted in every possible way from his late-2016 heroics. When you are broken in body and mauled mentally, why would you not seek an extended rest?
