I'm of the understanding that American opinion rates this seasons crop as one of the weakest for some time and in fact they thought So You Think would have a huge chance.
I've just checked and entries for BC are not being made until 24th October, so ignore anything you read about who is running until after this date!
Generally speaking if the bookies have scratched him, then he won't be running. For what its worth, if he did run and did handle the dirt he could win, his form is still pretty good at 10fs. Id rather have SYT than ATD who was well beat in the Juddmonte. It is a poor group of American horses, Uncle Mo is the hype horse and favourite but he has failed to deliver the goods this season, having looked much like Frankel in his 2yo days. there is also big doubts over wether he will stay the trip. So European radar's probably have there best chance ever of winning the Classic on dirt
