I’d agree with full book 2016 and likely 2017. Entire career, he’s gotta produce or it won’t be full (or he’s priced commiserate with an “average” TB stallion). I think Silver Charm is who I’m thinking of… just didn’t throw near his level of performance.[/QUOTE]
Silver Charm didn’t win the Triple Crown. Neither did FuPeg or Smarty Jones or any other of the Derby winners who fizzled out in the shed.
Secretariat, Seattle Slew, and Affirmed would be better comparisons-- all of whom had “full” books for their eras until they could no longer breed. And while all three were good sires, none of them truly lit the world on fire. Had they not been Triple Crown winners, they likely would not have seen quite the number and quality of mares. The Secretariat and Affirmed sire lines have all but disappeared; Seattle Slew’s is only preserved through AP Indy.
Today’s market is more fickle and more sales driven than the market of the 70s and 80s, but American Pharoah would have to be a colossal flop to lose interest from breeders.
