This may explain, from MST Facebook
I think you all are extremely hard on the commentating and maybe the posts on facebook will help you understand the challenges faced…or maybe you will feel the same.
Wow … what a wild day …… we are on , we are off, we are on , we are off…. and I mean the announcers not the riders ! At the start of our cross country live coverage we certainly had thrills and spills …. horses fell, ambulances arrived, the event was delayed and we were left up in the air as far as coverage was concerned. Obviously if a horse and rider are down on course , NBC breaks away to another event . We never know when they might return to us and when they do , we have no idea what rider or what jump they will show . We have to ad lib the whole way as we are not in control of the “world feed” which is the video we have to follow . We cannot decide who to show and when to run replays so what you see is what you get and the same goes for us as announcers. It keeps you on your toes and may explain a few gaffes here and there… so please bear with us 
The producer and director ,talking in our ear, do a wonderful job trying to bring cohesiveness to our broadcast . It is all fun and a great learning experience. I was so impressed with the British riders bringing all 5 horses home with no jumping penalties along with the Germans who remain on top. . They stand one two atop the leader board . We saw some terrific equine and human athletic endeavors today… along with a few unlucky moments for Aussie Clayton Fredericks, slipping down at the big drop and Oiwa of Japan getting unhorsed at the same place . Mark Todd went for the big one at the last fence on an exhausted horse which almost cost him everything if he had fallen … but still cost him first place … That extra stride his horse took to save the day cost him the .4 time penalty which dropped him from first to third by .2 of a point … It may not matter in the end but could be a heartbreaker that keeps him from Gold. Going last is never easy and Mark, a double Gold Medalist , looked as exhausted as his horse at the finish .
Sweden is surprisingly in third place followed by New Zealand . The Americans are still in striking distance of a medal in fifth place . Horses have to pass the vet inspection in the morning and then jump the final phase in the stadium . Anything can happen as we all well know .
Tomorrow is a new day and almost upon us so I will sign off for the evening and give you my thoughts at the end of the Team and Individual Finals for Eventing tomorrow … … the first Equestrian Medals of this Olympiad.
From the other day:
Hello All
The Games began for us today with Eventing Dressage . Three of 5 Americans rode their Dressage tests with average results as a Team. I am not planning to write a lot of details on results because that can be accessed at numerous official sites and by professional journalists. Just know that the Germans finished one-two today with Great Britain in third . The best American was Karen O’Connor in 9th., but we are only half way through the start list with the rest coming tomorrow . Boyd Martin had to ride first and probably was not given the scores he would have gotten if he had ridden later in the draw … Judges seem to hold back at the start, but that is the luck of the draw … or bad luck in this case. US drew first out of all the teams .
I don’t have beautiful on site pictures to share from now on so will have to show you those from the IBC. The picture below is “our venue” . Tim Ryan and I are watching on a tv monitor just like everyone without a ringside seat . It makes it more difficult to feel the energy of the moment but fortunately we were able to see and feel the facility in the days prior to the opening of competition .
