"Dancing With the Stars" Season 21 starts tonight (Monday, September 14) at 8 p.m. on ABC. Several weeks from now, in late November, one of the 13 crazy couples will be name the new Mirror Ball champions. Who will get the Fall 2015 trophy? Online betting site Bovada gave the best odds to former Backstreet Boys singer Nick Carter, who is paired with pro dancer Sharna Burgess.

It's not a bad pre-season pick. Nick, now 35, has name recognition, looks, probable talent, and enough mass appeal to potentially draw votes across age groups. Plus, Sharna is a very popular pro who has yet to win a trophy. It feels like this might be her time.

Here are the odds from Bovada:

Nick Carter +275

Alexa PenaVega + 300

Carlos PenaVega +600

Tamar Braxton +650

Bindi Irwin +700

Alek Skarlatos +1000

Andy Grammer +1200

Chaka Khan +1600

Hayes Grier +1600

Victor Espinoza +1600

Kim Zolciak Biermann + 2500

Gary Busey +3300

Paula Deen +3300

What do you think of these odds? As you can see, they tied Gary Busey and Paula Deen as the underdogs of the season. The oddsmakers are only occasionally accurate in picking DWTS winners, partly because they never seem to take a huge factor into consideration: the pro dancers. For example, Bindi Irwin is paired with five-time champion Derek Hough, who usually makes the finals and hasn't placed lower than fourth since Season 8.

Who is your pick to win DWTS Season 21 and why?
