I was reading Jack Kramer's old bio this weekend and one chapter had the former great American champion discussing the hypothetical Earth vs. The Universe Davis Cup team.Right now, I'd select Djokovic and Nadal at singles, Federer and Nalbandian at doubles. I'm leaving off the Bryans because they've lost their last two Davis Cup matches to much lesser Brazil and Serbia doubles duos.I think Federer would shine more in doubles right now, but he is also a question mark in the Davis Cup arena, you never know if he'll show up at his best. Some of Fed's Davis Cup performances have been surprisingly substandard, he lost to Isner in singles and also Rojer and Haase in doubles with Stan. Davis Cup has never been a high priority for him. It has been for Nalbandian, as the veteran Argentine has called Davis Cup his favorite tournament. But I'd still put Federer on my Planetary Davis Cup team right now. Who would you pick for your Earth's All Star Davis Cup team right now?
