Keeping it mysterious, I may not have guessed which colt you are referring to but, Rule #222 Jethro Gibbs "Horses which get into trouble tend to get into trouble repeatedly". From another perspective the last horse you remember making up much ground @ SA? Then again the surface is different i.e. deeper now?

IMO - your choice is not unreasonable, smaller outfits sometimes win Breeders Cup Races. As you point out Lasix may help maybe a lot In the end, the player must take a stand and a good price by definition will be contrary to the popular opinion.

PS The loss of two entries my help him get a clean trip. Maybe a defensive use?

Good Luck!
