That’s a pretty broad paint brush you got there. I know plenty of “SNTs” who stay SNT because, well, they suck at horsemanship. And plenty of BNTs who are damned good at their jobs and responsible horseman (and women). And plenty of the vice versa kind.
But yes, I agree with Midge. Assuming an honest mistake, I sure hope all the parties who were supposed to have had the real GG were actively trying to figure out why a former GP horse was all of a sudden unspecial at best in the children’s.
If I was a potential future client of any of the parties, I think I would be doing my homework just to make sure my sale horse wasn’t just allowed to show at the lower levels without so much as a serious discussion into what had caused the change. Not saying they didn’t do that - they may have had a dozen conversations about it trying to figure it out and just not noticing the ONE thing that was wrong was that it wasn’t the right horse. Just saying I’d like a little validation that if I was a client, and my horse wasn’t performing as expected, we’d be on top of it faster than this.
