Male Hottie: Kevin Richardson
For Him: Boy-band pedigree. Dancing has shown quite the fondness for pop balladeers, and it's time for someone from the best-selling boy band of all time to hit the parquet. On top of that, he already knows how to dance with chairs and hats.
Against Him: No success on Dancing will ever replicate the Backstreet Boys' millennial worldwide dominance.

Comeback Kid: Jodie Sweetin
For Her: The redemption arc works on Dancing (see: Steve-O, Lil' Kim), and Sweetin could be a good candidate: former child star, history of drug addiction, single mom. Besides, she's got a book to promote.
Against Her: She once hosted a show called Pants-Off Dance-Off.

Older Gentleman: Tony Danza
For Him: You know the former boxer's got fancy footwork. And according to Friends' Phoebe, Elton John wrote a song about him: "Hold me close, young Tony Danza."
Against Him: He wants to be the boss, er, teacher, not the student. Danza's pitching his own reality show to A&E, in which he will teach at a Philadelphia high school.

Blast from the Past: Melissa Joan Hart
For Her: She recently modeled her post-baby bikini body in a magazine, so why not flaunt it on the dance floor?
Against Her: She may still be bitter about getting passed over for Heather Mills way back in Season 4.

Male Athlete: Mark Spitz
For Him: If you've ever seen a dolphin kick, you know swimmers are very flexible. And Olympic champs (see: Apolo Anton Ohno, Kristi Yamaguchi, Shawn Johnson) have a flair for Dancing.
Against Him: We liked him more with the porn 'stache.

Female Athlete: Marion Jones
For Her: The former track-and-field star, who served a six-month prison term last year for lying to prosecutors about steroid use, can embark on a fresh — not false — start here.
Against Her: Jones, who surrendered her five Olympic medals from the Sydney Games, recently announced a pregnancy.

Wild Card: Carlos Leon
For Him: A triple threat: personal trainer, actor (Oz) and father of Madonna's child. Leon will be fit, able to get into character and full of tidbits about the Material Girl.
Against Him: Guy Ritchie or Sean Penn would be cooler.

Woman of a Certain Age: Susan Dey
For Her: Surely she's still got some rhythm left over from her Partridge Family days.
Against Her: Dey's been AWOL as of late and has a better chance of popping up on David Cassidy's Ruby and the Rockits.

Corruptible Youth: Kelly Blatz
For Him: He's the star of Disney Channel's action series Aaron Stone, which is chock-full of choreography.
Against Him: He went to the prom with Gossip Girl's Blake Lively, which means men everywhere already hate him.

Soap Star: Rebecca Budig
For Her: As a former star of ABC's All My Children, she's got a built-in audience of millions. She's also married to former Bachelor Bob Guiney, who can surely help her navigate the treacherous waters of TV fame.
Against Her: AMC alums Cameron Mathison and Susan Lucci didn't fare too well on the show.

Recording Artist: David Lee Roth
For Him: Re-watch the "Just a Gigolo" video and you'll remember the genius of terpsichorean entertainment that is Diamond Dave.
Against Him: He might be a little too volatile for live TV. Plus, he may want to devote himself to a reunion with Eddie Van Halen.

Talking Head: Melissa Rivers
For Her: She was raised by Joan, so we know she's a tough cookie, as she proved recently on Celebrity Apprentice.
Against Her: Working the red carpet may require stamina, but it isn't exactly exercise.

Big, Lumbering Athlete: Deion Sanders
For Him: The retired professional football (and baseball!) player was once famous for his "high-steppin'" end-zone dances. He's used to appearing on TV, with a day job on the NFL Network and an Oxygen reality show about his family life.
Against Him: His ill-fated music career.

Country-Fried Chick: Wynonna
For Her: She has recently emerged as a weight-loss role model in conjunction with her endorsement of Alli. Plus: A suspiciously timed press release that announces: "August Is Wynonna Month on ABC." You don't say!
Against Her: Her official Facebook page says she's on tour this fall.

The Fame Whore: Levi Johnston
For Him: He's got that bad boy thing going on. Ask any of your so-called respectable female friends. Eventually they'll cop to a strange attraction to Bristol Palin's ex.
Against Him: He doesn't seem like the sharpest shotgun in the shack.

Female Hottie: Elizabeth Berkley
For Her: The Saved by the Bell alum and indie-film actress has a background in dance (no, not Showgirls, before that), and her official website makes it clear that she would very much like to be a positive role model to young girls.
Against Her: Is Disney really ready to let the woman who did this appear on their wholesome family program?
