but this is more true about fillies than colts IMO...the breeding parachute will open wider for a well bred unraced filly with good siblings than it will for a colt in the same situation...
I don't think DOA will increase LM potential stud value much...

So, essentially, no matter how good she may get or how good her offspring turn out to be on the track, Lewis Michael would still be standing on just his own accomplishments?

I don't get the biology of how the traits/success is passed down very well -- do you know why it wouldn't work vice versa for Lewis Michael?
