Well, we have to get a triple crown winner before we know if he impacts the breed. With the Jockey club only allowing live cover he will be limited to the amount of mares he can breed. If he does win the Triple Crown, in all likelihood he will be syndicated & only those who have bought a share will get to breed to him.
Secretariet with all the records he broke & winning the Triple Crown was never much of a producer altho a lot of mares out of him produced a lot of winners.
i agree, the triple crown winner has to come first, before you know if he will produce.
though, that doesn't mean the weeding out process on potential canidates doesn't start sooner.
yes, he will be limited, but that doesn't mean there won't be demand in the form of his sons.
secretariat's daughters were producers largely due to the x factor.
