When your confidence is low, stuff happens like what happened in the matches vs Aga and Petra, Caro is desperately short of confidence vs top players atm.
I never questioned that Caroline works hard, or that she wants to be successful.
Its hard to focus & focus & focus, especially when you've done it and now have the material rewards.
Thats why what Vika did is very impressive. She had a great year, then came back this year, not only won her 2nd major, she beat Serena after she knew she lost her #1.
If she can keep the mental focus, Vika might be an alltime great. But the hard part is to keep the focus.
The big match in 2007 was Henin-Venus at the USO.
2008 Ivanovic, Jankovic, Safina had great years.
2010 the top 3 was Caroline, Vera, Kim.
To stay at the top for years is very hard, and the only players at the top now who were there before 2011 are Serena & Maria. They are 1st ballot Hall of Famers. Vika is closing in on that too.
What happened to Caroline is very common among good players. They cant keep the mental toughness. Even if Caroline is motivated, to actually win these long tough matches is difficult.
Hard mental & physical work
