Serbia are stronger than ever, so USA would have struggled to win the tie anyway (especially on clay)...therefore maybe not such a big deal.
However, Roddick's attitude towards Davis Cup has always been exemplary...but I wonder if his decision is more because of the crass Tour scheduling for this season? Holding Davis Cup ties in the week before the commencement of back-to-back Masters events was a pretty :retard: decision imo. Obviously he'd probably prefer not to play clay court matches (which he'd struggle to win) immediately before his attempts at some good performances in IW/Miami. Also needs solid finishes in those events if he is to push for another top 6-10 year finish.
It would probably also pay for Blake to be selfish...if he is to make a good comeback this year, he needs to be concentrating on Tour events on any surface but clay.
Besides, if I were captain of the USA side, I'd have binned him for the Switzerland tie 12 months ago, favouring Fish...and yes, I said that without the benefit of hindsight.
So, imo, James had outstayed his welcome a little.
I think it is almost about time that USA bleeds some new/less experienced players for live duty anyway. Querrey will have to step up to the mantle sooner rather than later, even if he will be out of his depth particularly on clay.
