At least with Hewitt you always knew he was giving it his all. At least with Hewitt, his effort was never in question.
Tomic just doesn't give a shit, and it's sickening, really. I was rooting for Roddick the other day, but even I was pissed with Tomic's total indifference.
different strokes to different folks. hewitt's racism for example used to upset me much more than any lack of effort in a match but i can understand how white australians in particular and most of MTF might think differently.
that said, i doubt tomic is the first player to tank or to give a poor effort in a set (third set in tomic's case in the match you cite). it just happens that some conceal their tanks better than others.
