“Good better best stallion” is a keyword term used in the horse racing industry to describe the three top-performing stallions in a given year. The “good” stallion is the one who has sired the most winners, the “better” stallion is the one who has sired the most stakes winners, and the “best” stallion is the one who has sired the most Grade 1 winners.
This ranking system is important because it helps breeders to identify the stallions that are most likely to produce successful racehorses. Breeders can use this information to make informed decisions about which stallions to breed their mares to.
