Yeah, he's half brother to BC, which in thorobred lingo means same mum, different dad. But this yearlings dad is statistically better and has a better record (as a sire) than BC's dad. So far anyway.
If the colt turns out to be an early 2 year old runner he could be making money by November / December this year, but being as valuable as he is, (and his true value will probably be at stud, not prizemoney) the wise move would be to wait until he matures before starting him.
They will have a pretty good idea later this year how good he is likely to be though, even if they dont race him till mid / late 2014.
