I like Mac as a commentator, but his comments about Murray were way off base. He called Murray's problems vs. Nieminen a "Rope a Dope", giving the impression that Murray was exaggerating to gain an advantage due to the fact that he got better quickly. Murray was definitely not faking. I have struggled with this issue since my mid 20s, and there was no mistaking the way Murray was walking and trying to serve. It can be debilitating, but given the right treatment, it can be fixed quickly. Most of the time, when I have tweaked my back to the extent that Murray did, one visit to the chiropractor will make it right, but without treatment, it can be a long road back. He had the right kind of treatment, obviously. One caveat, at least for me, is that my back tends to be a little sensitive for a few days after treatment. I wonder if Murray's back will hold up to the stresses of a two-week tournament. That being said, clay is a much better surface then hard courts with respect to impact on the spinal column.
