There is something 'physically wrong' with a lot of them, Bolero Andrew came out on the track looking broken down he was falling down in the warmups and promptly went out and crushed the field on the front end going away like a wild horse.
As far as whether TT cared or not, he's paid to drive, not train. You drive em all the way to the line...its up to the trainer and owner to decide when and where that horse will race again, you are only being paid to urge all the way to the end, the rest of that stuff is not your job.
With all that said, the horse didnt have a drop of pace and was probably better he didnt make a race he would have had 0 chance to get a check in...now, he's in the conso or something like that where he has a shot to get 4th or 5th if he saves ground on both turns.
So, it worked out well.
If there's something wrong physically with your 3 y.o in July, you do something about it, you don't keep racing like he's a $5,000 claimer. They should be happy there is no consolation.
I can't read TT's mind but there are many drivers who will not push a horse who is having a problem & any owner or trainer who disagrees with that is a putz & deserves what he gets - a 6 month layoff! But, again, I can't know what TT was thinking so I somewhat agree with your general idea.
