I feel like Jen will struggle at first to find her form. Obviously her body will dictate what she is capable of, but it will take her six months to round into form, in time for Wimbledon. (Maybe RG) The problem is, I think to be competitive, she will have to come back better than ever (again) to be competitive at the top levels. The top ten is looking very crowded and competitive to me. I think Jen will have a productive 2-4 years (provided she is healthy), but no slams, culminating in a farewell tour heading into the US Open 07 - 09. Or, maybe i will be eating my words on this someday, as Jen has certainly proved people, including me, wrong before.
