Sorry for the double post but upon watching the video again, I think he may have actually been off on that left hind before the pattern was ever started. At the very first, you can see the slightest bit of a head bob at the trot and that spin was way off and scattered, especially for a #1 spot horse/rider.
Good catch smrobs! He sure was off in the beginning. I thought the spin looked a bit sloppy. Yikes...I don't know that I would have 'rode' him out of the ring though. Then again I doubt they have a trail riding competition at the WEG...so Ill never get to know!
