Great reply Kev, so here comes my counter (well slightly, I agree with most of your points).
The perceived 'best' chaser they had from my own perspective was always Shattered Love, I had absolutely no problem in hyping her up for the RSA thread, only for them to then turn to the JLT, and win it really well, she lived up to my expectations, even if I got the initial race wrong. I was never one to mention Dounikos in as much light, so for that argument I'd still suggest their best chaser went to the JLT (I also had no hiding place should she had ended up getting stuffed, just re-read the RSA thread, I think I mentioned her a little too much :highly_amused
I actually don't think there is a set rule for where Gold Cup runners go with regards to the previous festival runs, Don Cossack (another Gigginstown owned) went RSA, then Ryanair (step back in trip) then Gold Cup, this years winner, as we know went from the 4 miler to the Gold Cup and then the Gold Cup again this year as we know, Road To Respect, who ran a cracking race this year given the ground conditions ran in the Plate (over 2m 4f) then the Gold Cup this year. We know Samcro is heading towards the Gold Cup, I think that is a given, and maybe I was a little too brash with my 'shove him in the RSA' comments, but I don't see why they need to send him for that race to determine him being a Gold Cup horse.
If you take the Sizing John route into account (bit of a freak one) too you could now say 'any race' from 2m to 4m could find a Gold Cup winner amongst it.
Do you think we worry too much about what races they run in as novices? If a horse is that talented surely the race he runs in leading up to his overall target is irrelevant, as a horse with Samcro's talent will likely win regardless?
My own thinking is they will want him to have the easiest race possible, ready for a tough campaign when he takes on the Gold Cup the following year.
