I have watched it a fair few times and still can't get my head round it entirely.
Cue Card looked the best coming down the hill, and then Sprinter Sacre loomed up travelling strongest coming to two out. Then push came to shove and both found very little, as Spirit Son stayed on past them, but not as strongly as Al Ferof who fairly stormed up the hill. The problem I have is that it was not Al Ferof finishing 'quickly' (in absolute terms) because he was badly outpaced from the top of the hill. Therefore, the others must have been stopping in front. I have had a close look at it and I should think Sprinter Sacre loses 10 lengths or so on Al Ferof from the second last.
The question must then be will he do the same this year?
He has the benefit of another year on his back, plus a breathing operation. That might well mean that he storms up the hill this year and people will be wondering why the question was ever raised. However, there still remains the possibility that he will do the same again. There can be no doubt that he found very little because he was the only horse on the bridle at the second last but there was no response once he was asked for his effort and his jump at the final flight was that of a tired horse, running on empty.
Like you, the way he travelled into the race last year is very reminiscent of the way he has travelled this year. The fact that he jumps so quickly, travels so well and is keen must mean that he will be handy, whether Barry Geraghty wants to be or not. He will jump or pull himself to the front. I am sure the pace will be strong, but in some ways the stronger the gallop the more likely he is to be in front because, relative to everything else, he will find the pace easier. That might mean he is forced into 'committing' earlier than would be ideal. Assuming that a few can keep tabs on him, no certainty I might add, he could then be vulnerable to a fast finisher up the hill.
Ever since the Victor Chandler I have been of the opinion that Peddlers Cross is the only one that has the requisite qualities for the task at hand. He himself has questions to answer but I would still expect him to at least make a race of things.
Sprinter Sacre is clearly exceptional but in many ways it is the extent of his brilliance that might be his downfall. His jumping is so good, he travels so powerfully and so keenly that he could cut his own throat when he is faced with the hill.
So to answer the question, there are reasons to support both arguments. He might but he might not. Decisive or what?!
