Unfortunately many trainers not in the limelight do not get the best of horse flesh to work with. They hope to one day, mostly by sheer luck, have a horse good enough to win a few races, perhaps be something better than average. It is their lifestyle, training, breaking and conditioning. These are the battlers, once held up as the heart of horse racing. I have seen a trainer, battling with this type of situation, get a very good horse, suddenly owners want their horse trained by said trainer. Once the career of the horse is over and the trainers stats suffer, the owners dry up again and it is back to usual. Of course, I am speaking from the past so perhaps things have changed and these trainers are useless. As a punter, it is easy to cull a race day field of horses trained by such trainers, maybe miss one or two winners. Just my thoughts, no expert.
