Guess we all know though...as he wasn't considered a great sire of sires, or a sire of great race horses, but a broodmare sire ...

HH Man O War was also known as a broodmare sire.  It is an often held belief that the broodmares are the gold, as exemplified by the term "Blue Hen Mare."  I am confused where you are going with this?
  
That's because Secretariat could not give his large heart to a son & only a daughter, & a dam can give it to a daughter or a son...

Again, my point is...What kind(how fast) of a race horse would Secretariat have been without thew large heart/gene that gave him more wind/stamina than the others...?
