Her game is all power/athleticism & minimal fundamentals...now that she has regressed in both categories she is getting battered by skinny white girls.

Serena should have passed up Graf a while ago in Grand Slam titles when she was feasting on run-of-the-mill Eastern Euros to even have a shot of being considered the GOAT. Her run is over ala Tiger Woods.
