Yeah, the DFs were painful for sure, but today at least I think that was entirely due to nerves. By the end of the match I had the feeling that Sam’s arms and legs had pretty much turned to jelly. Not sure a serving coach can help her with that. But in general you’re right: for somebody who serves with as much topspin as Sam does, she hits way too many DFs.
My message to Dave is that they need to work on something, anything, that Sam can rely on and go to when she is choking. Like that one 'silver lining shot' or serve that she can depend on without having to think about, even in the midst of a massive choke. It's hard for me to explain this, but the problem is not all in the head. If she is beginning to get shaky and chokey, there should be a safety net for her to go to, i.e. "Ok, I'm nervous and choking and I'm probably going to lose but I can still place a really mean serve right into her body without overthinking it."
I know I'm asking for a lot, and hitting big serves like she does lends itself to more DF's naturally. But she needs a consistent, solid serve that won't crumble at key points during a match.
On a different note, fuck facebook. And twitter.
Oh - and my thoughts about 'weak minds' = choking. Weak minded people don't choke nearly as much as 'strong minded' people. In my opinion, weak-minded people don't maintain a clear perception of reality at all times and are often pleasantly aloof, walking through life with mostly no worries because things just seem to go in their favor (not really, but when you have a small window of perception, expectations are low). Strong minded people have hard and specific goals, crystal clear situational awareness, and a focus or drive to move in a certain direction. They think way too much about everything. So I don't like it when people claim that Sam chokes because she is weak-minded.
