In the Derby, Borel looked back yards before the wire and stood up in the irons( in his moment of celebration) BEFORE he crossed the finish line, and SS sort of lost his focus and hesitated just a bit. In the Preakness he turned around and looked back again (instead of looking under his arms) and in his own words admitted SS lost focus in the last few yards. Horses are creatures of habit, and the smart ones can learn with only one \"lesson\".
