Sprinter Sacre looked good on his fencing debut but I don't understand all the excitement about it. For some reason people seem to get carried away with 'spectacular jumps' when a horse is fired in long. I would far rather have a round such as that shown by Peddlers Cross (quick, economical, clever, etc) on debut than that of Sprinter Sacre.
Most horses can pick up long, but the hard thing is getting in close. They learn very little by being fired at fences, and it can go wrong too. They need to learn how to handle a long stride, but most find it relatively easy. Dealing with a short stride is far harder. Furthermore, it isn't necessarily the best route to a quick and efficient round.
As an example, just watch Ruby riding a novice. He lets them get in close so they learn how to adjust.
As for comparisons I would have given Peddler's debut round a 9/10 (or even a 10, it was virtually perfect in my eyes) and Sprinter Sacre 8/10 (he was a bit 'novicey' at a few early on). I loved the way that Peddler's was so quick and neat. Very fast and economical and no even slight hint of any greenness. He looked like he'd been doing it all his life.
Both were good, no doubt about it, but how anyone can say Peddler's didn't look a natural is beyond me.
