“Although Big Brown is by Boundary, a sprinter who has sired only sprinters and milers, it must be noted that Boundary is by Danzig, and his dam, Edge, is by Damascus out of the top-class stakes winner Ponte Vecchio, a daughter of Round Table. Big Brown’s dam, Mien, is by Nureyev (by Northern Dancer), out of a Lear Fan (by Roberto) mare. And Big Brown is inbred top and bottom to Damascus, Round Table, and Northern Dancer, giving him a Classic-heavy dosage profile of 4-7-23-2-0 and a 1.67 dosage index, for all those who still follow dosage.”
