I cannot see where anyone is coming from with this 'Denman didn't want to be there' nonsense. Let me tell you now; if half a ton of horse - nevermind this horse who undoubtedly is bigger even than that - doesn't want to do something, it doesn't do it. Period. Full stop. End of story. You think 10st of jockey is going to make an immensely strong horse do what they want them to do and nothing else? Think again. So there is an obvious flaw immediately in all the 'he didn't want to be there' arguments.
Now, onto the rest of it, concerning the horse looking bad and running badly, yada yada. Denman looked very well, and was striding around the paddock quite happy with himself. He may not have travelled like the bull that he can travel like, but that in itself does not indicate that he was tired/not wanting to be there/still affected by infamous and dubious 'problems' [delete as applicable] at all. It was not a tired fall Denman took, it was a simple mistake at a fence at which many other horses make the same mistake; the fence itself presents somewhat of a false groundline/optical illusion for the horses so some take off at the wrong time. I am quite sure that had Denman stood up he would have won the race; he was responding all the time, and responding well, to his urgings from the saddle, and was in my opinion going to get the better of Madison De Berlais. (and no, before anyone asks, I didn't back the horse)
