JB believes he is in the business of horse racing, not even the actual horse breeders are in the business of horse racing according to him*, mind you, but he believes he is.
I believe, in actuality, he is in the business of gambling and peddling gambling data. A horseman he is not, though his data can be very good, very useful.
And so is the DRF. TG distills the DRF, and other data factors, for those who can’t or won’t take the time to learn to read all those little numbers at once.
Likewise sabermetrics, the numbers guys don’t play ball. They consult and get paid for it but their data analysis. They are not ball players.
