I do follow racing, but I don\'t pay any attention to what historians, the general public, or DRF talking heads write about it, because you cannot count on any of them to understand the underlying data.
You\'ve got me on the \"class\" thing however, because so few races are run at this level, and of those, so very few of them run on off tracks or in situations where 90% of the field has no off-track experience. But I\'m sure there at least 10s of examples, if not hundreds, of horses that have jumped from the 5,6,7 range to the 0,1 range 1st time on the mud, regardless of \"class\". That\'s what happened here I\'m guessing, and if so, there is PLENTY of historical data to explain it.
Your assertion of completely unexplainable provides fuel to the fire of the drug conspiracy theorists, whether you believe it was drugs or not, and I think it does a tremendous disservice to the horse and its connections. I\'ll happily eat my words if it does turn out something was amiss, but for now I think this horse should be celebrated and not questioned.
