Puffin Billy is the perfect example of an Oliver Sherwood training master-class.
Win a couple of poorly contested/soft novice hurdles, get the horse handicapped way beyond it's capabilities, and spend the next two years watching it get hammered out-of-sight. Try fences, and when that doesn't work, drop it quietly back into a handicap hurdle, in the hope that:
a) the race cuts-up horribly, or
b) It's able to win from a mark just 7lbs lower that the one the handicapper was compelled to give it, due to the idiotic way in which it was campaigned two years previously.
Now.......need I say any more?
