For a few years now, NetJets has run a commercial featuring Roger Federer dragging a cart full of trophies across an airport tarmac. It's surely a fitting image for a man who's acquired as much hardware as the gilded Swiss. In fact, if you compare his record to any of the would-be GOATs (Greatest of All Time) there are only a couple of omissions. He never won the (true) Grand Slam (OK, well only two men ever have, we can give him a pass there), nor Olympic singles gold (an event known for "funky" results, Rafael Nadal's form run in 2008 notwithstanding). Federer's also never won the Davis Cup. That omission is a bit less forgivable, especially after his 0-2 performance this weekend on Swiss indoor clay against Team USA.
