I remember Henry Cecil hitting rock bottom in the 90/00s when Sheikh Mohammed pulled his horses from his stable and along with personal tragedies like his brother dying and ill health. I never thought he could get back up but he did when Light Shift won the Oaks and of course his superb handling of Frankel. He went for years without a Group 1 winner and dropped into the 90s of the trainers table.
The more I know the less I understand.
