How Cool, a breeding observation! Right up my alley.
Not being critical, but how about his (Not This Time) half brother Liam's Map?
His first crop found both Basin (G1 Hopeful) and Wicked Whisper (G1 Frizette) near the top of their respective divisions.
Thank God for Not This Time. After siring the wonderful Shamardal in his first crop, and the good sire First Samurai in his second, it has been a series of disappointments.
I want to add Curlin's sire son Connect to the list, but would need some leeway. He sired the above mentioned RNR (Grade 1) as well as the G3 winning filly Hidden Connection, who goes Saturday at FG versus the champ Echo Zulu.
I found an interesting connection today by chance. The last Classic winner KGM saddled was the filly Swiss Skydiver, one of only two runners to defeat Authentic. She was out of a Johannesburg mare, as is RNR.
I could go on and on but don't want to put anyone to sleep.
