A strong argument could be made that the two are connected. If she can improve her game that should make it easier to improve her consistency.
Maybe. I think she knew how to use her skillset, and was very successful even with limitations.
Like I said, Caro & Kim won everything above Tier 2 for nine months. From after Serena won Wimbledon 2010 right thru IW 2011. Even after that streak was broken when Vika won Miami, Caro still won about 10 matches in a row, winning Charleston & reaching the Stuttgart final
This is a different player now, but she doesnt need all these improvements to beat Pervak, Mchale, Muguruza, and a lot of players she lost to. Look at those last 2 points against Kvitova from 4-5 deuce. We werent shaking our heads at how she could make unforced errors like that in those key moments, 2-3 years ago
It might be hanging out with Rory, who has a 30 year career ahead of him with no majors until mid-April. He's very laid back, confident he can lose form for months & then cycle back and still win a major.
In tennis, very few players fall back like Caro did, without a big injury, then cycle back.
Usually its like Jankovic and Ivanovic, where its very hard to get back the consistency and confidence in tennis
