Roger Federer Goes 0-2 in the 2012 Davis Cup

Roger Federer losing to John Isner in singles as well as losing the deciding doubles point for Switzerland will go into the files as one of his worst weekends.  Going forward it will be interesting to see if Federer is suffering from tour fatigue or if this was an aberration.  With Andy Murray looking to make a charge and with Novak Djokovic and Rafael Nadal clearly out in front of Roger at the moment, motivation and concentration will be key to his 2012.  I think Federer will be fine and he has been beyond consistent in his career.  Even Roger is entitled to a bad weekend now and again.
