Despite the start of the NFL season, two of the top three spots in this week's rankings were reserved for the U.S. Open champs, with 15-time Grand Slam winner Serena Williams taking the crown. Williams dominated the field until the final, when she won a grueling three-set match against Victoria Azarenka, grabbing the attention of our panel. Andy Murray's first career Slam title was good enough to give him the third spot.
Breaking up the tennis monopoly at the top was Redskins phenom Robert Griffin III, who put together one of the best debuts for a rookie quarterback in NFL history. Griffin threw for 320 yards and two touchdowns to lead Washington to an upset of the Saints in New Orleans, one of the toughest places for a visiting QB to play in the NFL. After one game, Griffin is probably already popular enough in D.C. to run for office in this election year.
That's how our panel ranked them, but do you agree? Let your voice be heard in the comments, and if you impress the panel, you could be chosen as a guest ranker for next week.
