Re: Peak Ivanovic vs. Peak Sharapova
This is actually a misconception. Maria at her very best actually rarely hits MASSIVE (90mph+) shots in terms of pace.
What makes Peak Maria so brilliant is that she gets such fantastic length on her shots and can land every ball within centimetres of the baseline - the type of control that Peak Ivanovic could only dream of getting with her forehand (even if she'd occasionally hit a pacier shot than Peak Maria could, her average rally ball would be far more innocuous and land much shorter than Peak Maria's rally ball). And that's before you even consider that Peak Ivanovic would be hitting more shots out than Peak Maria would.
Yup. Plus Maria's best shot is her backhand crosscourt, which would drive Ivanovic nuts. Ivanovic is actually a pretty good junkballer, but Maria would just smother her from the baseline.
I actually still think this match would be close, but still NID.
