I actually had Shishkin down as more of a Ballymore horse (though had backed him for both novice races) before the Festival, tbh, and was just as pessimistic as you 6f out in the Supreme.
To this day, I still say Newbury was more of a staying peformance than a turn-of-foot 2-mile performance, and the way he clawed back the ground in the Supreme, hasn’t done a whole lot to dent that view. It might be the case that both horses are/were classy enough to win G1s at 2m when actually wanting further.
Crab Shishkin’s Kempton form if you want, but novices have to start somewhere, and only a fool would suggest that Envoi Allen duffing-up the 128-rated hurdler January Jets in his maiden chase, was the extent of his talent or ambition over fences.
You are clearly an Envoi Allen super-fan. That sits OK with me, as I’ve been there before with Hurricane Fly. But, much as I did with the Fly, if you make assertions that are largely based on faith/expectation, and open to some interpretation formwise, it’s only reasonable that you can expect others to take a contrary - or perhaps slightly less rosy - view.
The simple fact is that saying Envoi Allen would beat Shishkin over 2m can’t be backed-up with any objective measure, other than the relative results against Abacadbras.....which makes them close enough as to be arguable either way, depending on which ‘camp’ you happen to be in.
Better we just celebrate both horses, hope they fulfil their full potential, and that they meet one day in a competitve scenario over fences.
