Here's an intersting thought, people said there would never be another Man O War, then there was Secretariat who in my opinion was just as brilliant as MOW. Will there be another Secretariat? There have been a few horses who could of won the Triple Crown I see them as Point Given or Afleet Alex who both relished longer distances.
I agree I'd take a distance horse over a sprinter any day. Part of the reason I've shyed away from Curlin is the pedigree and speed, if he and Street Sense run in the Belmont I wonder what the result would be.
It's hard to compare decade's to decades but speed is almost higher up on prority for breeders theses days. Alot of the older stamina bearing sire's are getting older, i.e A.P Indy, Dynaformer, the last blood we have to the great's Secretariat, Ribot, Nasrullah and Seattle Slew. There was certainly a broader range of speed and stamina in the olden days when you could seperate a sprinter from a distance runner, not trying to run them all in the same class.
Another aspect may be greed?! Which might be why we see more sprinters show up in the classic distances. bigger purses more glory.
Street Cry is an intriguing new sire with some distance pedigree.
