As usual, tennis_pro does a very bad job of expressing himself but he has a point. I don't find the new players on either tour to be very well rounded, with perhaps the exception of Muguruza. And I have no idea why she went into this slump but hopefully she is back on track now. Say with Konta, you can see once she gets a lot of heat from the other side, her forehand side starts to break down. For not being the biggest hitter on the tour, she overhits way too much. Ostapenko could turn out to be a great player if she improves her serve. But that is a big if. Ivanovic never fixed her serve, for instance. OK, forget Venus or Henin, none of the new players have the range of an Azarenka. Another player who I thought would win many more slams than she ultimately has, at least to date. And remember, all this is with Serena in absentia. It's going to be a huge problem to fill the void when she leaves and of course an even bigger problem for ATP since they have four huge stars with Wawrinka as a bonus attraction. Tennis is in for a slump in the future unless there are indeed some upcoming players who have so far flown completely under the radar and will take over from these great players when they are done.
