When you have a leaderless tour full of players, who cannot dominate, the one has to emerge above all and win more than others...it's not like women's tour these days has multiple dominating players equivalent to big-3 or something...it has old Serena, who isn't even dominating anymore and still manages to look the most consistent even without winning multiple slams a season or even a single slam! If anything, that says a lot about sorry-butt state of women's tour than about the strength of it's players...
So all things considered why Sloane couldn't be that player??! It's not like she was getting blocked by someone like female versions of Djokovic, Federer or Nadal, so why the heck not?...
In the current state, women's tour finds itself these days i expect ANYONE at all to step up and start winning everything...if this keeps up - it's no brainer it'll inevitably happen one day! One day some player will use weakened tour to her advantage and will start winning more than others by dominating for a few seasons until next truly great player arrives and does something to her, what Federer did to Hewitt and Roddick back in the day...in fact i expect Halep to have one of those "ATG-tier" seasons when tennis resumes after COVID, if not in 2021, then maybe in 2022! She definitely more than any other player now has capabilities of pulling off a couple of multi-slam seasons back-to-back...i can totally see it happening from mile away!
