Whoa. There's a lot here to unpack.
I don't have a lot of time, so just a few things.
Let's talk about the so-called laziness issue. I am stunned that anyone would consider any elite female athlete who has risen to be one of the best players on the planet to be lazy. Sure, Bernard Tomick and Kyrios are straight-up lazy, but . . . **they're not women, are they?**
I do not think top WTA players are out of shape or fat. I admit that I don't know much about unseeded players -- they come and go in the early rounds when I'm not looking. But come on. Here's a list of the top WTA players:
Halep
Woz
Muguruza
Zvitolina
Pliskova
Ostapenko
Garcia
Williams
Kvitova
Kerber
Conta
Georges
Stephens
Keys
Mlednovic
Kuznetsova
Kasatina
Sevastova
Note that Serena, Maria, Azarenka, Stosur are not even on this list. Now, how can you say any of these women is overweight or out of shape? Should I keep going? 'Cause I scanned the top 100, and I didn't recognize every name but the only one who I would say could maybe stand to lose a few pounds is Kaia Kanepi at 59. But hasn't she had health problems? And maybe Kvitova is heavy, but you know, she got *stabbed* not so long ago.
As far as the idea that the women need to learn to serve to the BH . . . . I'm not following you. Do you really think female pros step up to the line and don't bother to place it? Maybe they don't serve to the BH because the BH is the stronger wing of their opponent? Or maybe they want the return coming back to their FH?
Yes, there is a strength element to serving, and men are stronger and usually serve harder/heavier. Women have different attributes, so they play differently. The variety makes for way more interesting events than if everyone were the same and played the same. I say nobody is doing it "the wrong way." They're all right in their own way.
