The one agonizing aspect of the Belmont is the mystery surrounding Big Brown's performance. We've heard many theories, and that is what they will remain. No one will ever know for sure why a horse that personified perfection suddenly came apart at the seams. Was it the deep track, the stifling heat, getting rank early in the race, the traffic and bumping going into the first turn, acting up in the holding barn, missing four days of training, possibly being dehydrated, sweating between his legs and not much on his body, breaking awkwardly, possibly getting spooked by the starter in a blue jacket and white pants standing right on the racetrack,? It likely was a combination of occurrences that led to his shocking performance.
