I've said this before -- though probably not here -- at least, I think not -- my memory is so bad sometimes -- anyway, as I was saying... hmm. Let's try again.
I've said this before, but every time Roddick starts to get nervous on court, I'm struck by his uncanny resemblance to a restive race horse. It's all there: pacing about nervously, shaking his head, chewing on his towel... (All right, so horses haven't got towels to gnaw, but you get the point, I hope.)
So, there you have it. What he really needs might just be a horse whisperer.
That's my theory, anyway
