djokes career was doomed when he gave wilson up for head. hes but a shadow of his former self these days.
That's not really true,he played plenty of good tennis with Head too-clay court season last year,Cincy,autumn run where he beat guys like Verdasco and Soderling(as well as Roger and Rafa,although they were obviously far from their best) but it's people like Verdasco and Soderling etc. who he has lost to on a regular basis this year that he was beating last year with Head.So I think the problem is the serve which on the first day of the year after the off-season looked awful(thanks to Martin
)and he has lost heaps of confidence from that
