Way too overbroad for TB racing. What if you run a horse in partnership with owners that also run horses in multiple states using 5 or more trainers. One of those horses–which you and your trainer have nothing to do with-- gets tested for a Class 2 drug in picograms. So your horse gets benched?
Maybe that works in harness racing because it’s so much smaller but I can’t see it in TB racing. Rather than do stuff like this, I’d like the regulators attack the Lance Armstrongs of the sport where anyone with a sense of history knows something doesn’t compute. Trainers that win at the biggest circuits at a 30 % clip, horses that never seem to tire in the stretch, trainers who toiled in obscurity for 10 years and suddenly overnight have horses that seemingly can’t lose. I’d like a rule that when a trainer hits a certain tripwire–win percentage or what have you–that the barn is subject to extra scrutiny. But the regulators would have to have the stomach to take on some of the biggest names in the sport and personally I have my doubts that would happen.
