12. Martina Navratilova and Tony Dovolani
The tennis legend's lovely, if safe, foxtrot was a perfectly respectable debut dance that probably would've ranked scored higher any other season. But she's in a three-way tie at the bottom of the leader board and brings up the rear in our rankings. With the jive next, the 18-time Grand Slam champ is gonna have to show the same attack on the hardwood that she showed on the tennis courts.
