I think the word banjaxed came to mind when he arrived. Attention to detail is key and they eventually found a foot problem with him. Once that was sorted, the wins kept coming and coming.
But I've come to the conclusion that anyone of us could train a horse to win if we sat in a yard for a few months and soaked up how to get a horse fit. I think the good trainers (and what would set them apart from the chancers like those in the previous line) are the ones who know when to stop, when to go, what's wrong and why its wrong and get it sorted. They are the people that win with horses that shouldn't win. And they aren't high profile horses. It could be a little handicapper with a back problem or something else.
