Drosselmeyer's stunning win in the Breeders' Cup Classic has thrown the Horse of the Year debate into overdrive.
A horse with just one win since the 2010 Belmont Stakes could hardly be expected to contend, much less capture the year-ending showcase. Yet here he was, surging past Game on Dude in the stretch for the upset.

So now, who's the Eclipse Award winner as Horse of the Year? Havre de Grace, the impressive filly who finished fourth in the Classic against the boys after an brilliant season against her own gender? Jim Dandy and Travers winner Stay Thirsty, who was the runner-up in this year's Belmont Stakes?

The Classic race winners aren't in the running this year. Kentucky Derby winner Animal Kingdom got injured. Preakness winner Shackleford was beaten in the Belmont by Ruler on Ice.

With no clear-cut favorite. This race is anybody's guess.
