Stallion success is measured by the quality of the runners they produce (sires of runners)... and whether or not any of their sons become successful sires (sires of sires) ... and/or if they produce a string of daughters who become successful broodmares (sires of broodmares) ...

... not by the number of bets you cash on claiming and allowance races.

Sires of Runners: There is a statistic called the Lifetime Average Earnings Index (Lifetime AEI) ... which provides a good measure of success as a sire of runners. Only stallions with Lifetime AEI's above 3.00 are generally considered to be successful sires of runners. I don't have that figure for all of the stallions I cited ... but I doubt if any of them are anywhere near 3.00. Also important is the percentage of stakes winners ... which should be above 10% ... and as high as 15% or more for the great stallions. None of the stallions I cited comes close to those figures.

Sires of Sires: This becomes evident when a stallions sons go to stud. It's a bit early for some of the more recent horses on my list ... but it's highly doubtful that any of them will produce one or more sons who are success at stud.

Broodmare Sires: Same as Sires of Sires ... but on the female side.
