barbaro brother by a long shot
there are approx 50,000 new foals born, 1/2 male (fillies dont win triple crown races too often) so that is 25,000 with a shot, and of those considering breeding , bloodlines, connections, only a potential 10% are in the mix for triple crown per year.
so Barbaro brother has a 1 in 2500 chance in my opinion to win a triple crown race.
the Jordan kid (he might have the size, but all the other factors he might or might not have) Id say the kid is is 1 in 20,000 or so to dominate the NBA in some fashion?
