The suggestion that 'the public' give a toss about racing - even its greatest stars - is 100% bogus, in my view.
We exist in a bubble. No-one outside that bubble cares what happens within it. The last genuinely 'public' jumper to have raced is Desert Orchid. Notions that Best Mate and Kauto Star were ever 'public' horses are misplaced, imo....as are notions that Sprinter Sacre will become a 'public' horse.
That said, it's legitimate for those that do exist within the bubble, to want to see the very-best horses tested to their limits.
I don't think that's a particularly big ask, but connections of such animals appear to be too afraid of their charges actually losing a race - regardless of the circumstances under which they compete. That - for me at any rate - is one of the most disappointing aspects of the game. You just don't see many of the 165+ brigade (hurdles or fences) being tried in anything other than optimum conditions these days, and it's to the overall detriment of the sport.
