Cov,
Everyone gets ahead of themselves too far before big race days.With very big fields, the post position draw is critical. In the case of Indian Bleesing, I see her figs tower over and her spacing is good enough. If she draws the rail and has speed right next to her,she could be vulnerable from a trip standpoint.
I am not as certain as you that Indian Blessing,or any BC participants,will run their normal dirt figs on that new surface.
