And, If you assume that only the best horses were being bred to each other (they weren't) back when the foal crops were so small---than there is no way John Henry would have existed.

Spectacular Bid's 2nd dam was a very mediocre horse, and his dam raced on the Northern California fair circuits. He's another that wouldn't have existed.

Secretariat's dam never won a race, but she came from a very good family. Affirmed's dam wasn't much horse, and she had eight siblings, none of which earned black type. Cigar's dam ran 7 times and never won.

Seattle Slew was sold for like 16K or something at auction.

Ah, but those are modern examples you are using! And regarding breeding lines if you equate "best" to track performance, you are way off base...many Blue Hens did little on the track, breeding is a lot more complicated than simply looking at records of dam and sire.
