This isn't me -- I neither play nor look like this -- but I'd be interested to see what level people thing the person closer to the camera is. It's obvious that he's good, but is he 5.0? 6.0? World number 2? You only get to see groundstrokes, so it's difficult to tell accurately, but can you get a rough idea?
