Our can't-miss predictions for rest of 2016

The ATP and WTA just finished providing us with their first-quarter reports. One was quite a surprise; the other, not so much.

Surely, no one who has been paying attention since 2011 can be puzzled by Novak Djokovic's success so far this year. Conversely, who would have guessed that the first three months would go by without Serena Williams winning a title? That's a genuine stunner.
