I'll bite and say no; there are too many great jockeys to pronounce McCarron the best. I just watched 3 races, 2 classic distances: the Breeders Cup Classic with Sunday Silence and a great ride by McCarron, no doubt. The only things better, the horses performance and the race call by Tom Durkin. I also watched the 1976 Derby (a great ride by Angel Cordero; another one in the Belmont) and though I always couldn't stand Chic Anderson (he called Bold Forbes Belmont), I look back now with fond memories of Chic being unable to get the screeching of Larry Colmus out of my head after most races. Sorry to Chic fans; didn't appreciate him enough (actually at all!) and honestly didn't remember that he'd passed away almost 40 years ago at 47 (heart attack), replaced by another I'd gladly take now over LC, Marshall Cassidy.

So in answer to your question, an unrelated question for anyone wanting to comment, related to announcers: Anyone better than Durkin, or worse than Colmus?
