She needs to sustain her level of athleticism constant or even raised it to another level, Ivanko didn't put much needed sense of urgency on that which led to injury and loss of form which improved a bit as season progressed.
I'm not telling you Ivanko is/was perfect. Cause he was not.
But my question is, how could Petra had done that, when she got injured in Dec 2011, then missed out on her training, sick in Doha and Sick at Indian Wells (plus she took of 3 weeks during the middle of the season, during Doha/Dubai/before the US spring run, doing nothing to heal her achilles).
Now, I still blame those things on her team, but it's expected your results and conditioning are going to be below par, if you're intermittently not playing or practicing.
Last year during the spring, she wasn't used to that type of winning (like most players that would of been in her position, just like after Wimbledon 2010.
I know what you're getting at. But it's not always that cut and dry. The bottom like is, either way they screwed up with certain decisions, which impacted Petra's season, and we don't need to see it again.
