#3 The emergence of the NextGen
This season has definitely seen the NextGen players take a step forward and challenge the top players. Hyeon Chung reached the Australian Open semis while Borna Coric reached the last four at Indian Wells. Thanasi Kokkinakis upset Roger Federer and Denis Shapovalov continues to impress. And that's not to mention Dominic Thiem who has already turned into a clay beast.
Thiem and Alexander Zverev have powerful baseline games which is one of the prerequisites for success on clay, while Coric and Chung have the consistency to rally with anyone on slow surfaces. This could well be the year that one of them breaks through and wins the French Open.
