So You Think was also a much more battle tested horse well before O’Brien got him from Australia (where he was already a 5 time G1 winner and in one season he won over 7F on soft ground and finished 3rd in the Melbourne Cup over 2m on soft ground) yet he still only managed 6 of 12 in the Classic.
The winner that year was a horse that only won 3 of his 11 career starts and started at 20-1 with the second and third both at 14-1 (So You Think was one of only 4 of the 12 strong field that started at single digit odds). So not exactly a classic Classic….pardon the pun.
Not saying it can’t be done but having a specific type of horse that will be adaptable to the grueling conditions and has somewhat of a dirt pedigree can only be a massive help – but this is a horse that has some questionable performances (without explanation) and to me isn’t a horse to be putting your trust in when facing very alien conditions to any he has known previously for the first time.
