How do you figure
 

First two races today at the spa, J R not on either of Pletchers horses opting for others. Of course Pletcher has Santos and Prado. Does this signify anything? J R is back on AP Arrow in the third. Should we give more weight to the horses JR is on in the first two?

I am. Out of respect for his agent, who probably made the decision.

With the lack of inside info, I always wonder which way it goes? Does the owner/trainer take them off or does the rider opt of for a better mount?

well it never hurts to have a hall of fame jock and one who still works horses as your jock agent.
