I think there will be..... Real Quiet, Silver Charm, Charasmatic, Funny Cide, Smarty Jones, Big Brown, and that big red horse of Bob Baferts that won the second two races but not the first (Point Given I think is his name), all show that horses are capable of it. Barbaro was a huge loss because it will be speculated for years to come on how he would have done had he not broken down....... Yes I think there will be. Thank goodness not this year.
On a side note, I also think that people should not name their horses unregal names like Super Saver.... who would want that to be the next horse legend?
