With the memory of Barbaro still fresh, Eight Belles' catastrophic breakdown Saturday put increasing focus on a sport already trying to overcome a decline in popularity.

Her death has raised thorny issues about the whole thoroughbred industry, including track safety, whether fillies should be allowed to run against colts, and whether horses are bred too much for speed and not for soundness.

A prominent animal rights group got involved Sunday, too, criticizing Eight Belles' jockey for whipping the horse and saying the second-place prize should be revoked.

But to horse people, it wasn't all that simple. "To make it safer, don't race the horses, don't train them, then they'll live good lives out on the farm," Big Brown trainer Rick Dutrow Jr. said. "But you have to train them for races, you have to run them and that's where the problems start to set in. They have to be asked to run and sometimes in a particular minute, they're asked to run when they're not ready to give it and then it hurts."
