Check out this slideshow from SI.com which gives information about each horse in the 2012 Kentucky Derby, the post positions, and the current odds.
The video in this post features Dullahan, whose odds in the derby are 8/1. This, from SI:
His critics will say that he's winless in three starts on conventional dirt, including a fourth-place finish in November's Breeders' Cup Juvenile. His supporters will argue that Dullahan has improved significantly since those three dirt losses and has the best closing kick in a race that should favor late-runners. Either way, the Dale Romans-trained chestnut colt, who defeated Hansen in the Blue Grass Stakes last time out, will enter the starting gate as a legitimate contender for the win spot.
