Horse Conformation Flaw or Not?

Notice how this horse’s hind fetlocks almost touch the ground. What do you think will happen when this horse stops hard from a lope? Let me know what you think. BTW, I muted the audio because of too much wind noise.

I killed two days, a plane ticket, a rental car and hotel bill to go look at this 3-year-old futurity prospect. Time and money well spent?
You tell me!

Take care,
