This is true. Heck even horses who have small chips removed rarely if ever come back to what they were before the chip.
Tendons? Well maybe if you give em 2-3 years they can be ok. Fractures? Well sometimes it works with the screws but most of the time it doesn't.
I still find it hysterical that the guy won yet another championship last year and that at his age people hold him up to scrutiny as if he were a spring chicken.
The bashers sure see something i don't see and I will cite two glaring reasons why.
1) Many breeders I know will not go to a new sire they feel was trained by a "juice guy". There are several trainers who have trained a lotta good horses and have yet to have trained a really good sire.
D Wayne has trained many great or good sires. Dynaformer, Carson City, Capote, Cat Thief, Gulch, Grand Slam, Honour and Glory, Jump Start, Is It True, Yes Its True, Mt Livermore, Orientate, Slew City Slew, Salt Lake, Thunder Gulch, etc.
If they were all moved up so much by his "mystery methods" why do they still produce in the shed unlike many other name trainers horses?
2) The guy obviously has been a tremendous teacher of horseman. Todd Pletcher, Mark Hennig, Randy Bradshaw, Bobby Barnett, Dallas Stewart, Mike Maker, Kiarin McLaughlin, all learned under him. What are the chances that he doesnt know horsemanship with a roster of pupils like that?

Guys trained so many champions and grade one winners its too long a list to name. Hes also 71 years old. I think I'll cut him some slack.
