You are asking for a sportscaster.
NADAC scoring is not instantaneous which would also not allow for your example, You may know how close 2 dogs are to each other but you would not know the score that quickly.
Would have to be coordinated with the Live stream provider yet possibly not recorded for the person paying for the video since they would want the audio for the run with the PA announcer and no sportscaster.
Interesting thought but Four legged Flix or some other video company may not want this complication of a service they are trying to make money with.
Sportscasting is a talent and doing it for a sport which is not commonly known is a difficult ask and if not done well is not worth doing.
All excellent points. I will say there are other sports with a sport caster that are subject to final review -- horse racing, many Olympic sports like track and field or speed skating. I agree sport casting takes a talent to do well. AKC had ESPN recruit a couple talented agility people. Four Legged Flix would probably not be able to do this on their own. But I think the people NADAC has announcing now over the PA have the talent and knowledge to do it well. I might be in the minority but I think it would be cool if I make finals to have the sport casting sound in the personal video I pay for.
I realize NADAC is not ESPN. They are not going to have multiple camera angles and fancy charts and displays. (frankly I found the multiple camera shots took away from what I wanted to see) But I do think AKC brought in new competitors to its venue because of how they did broadcast their finals with sport caster style. All I am saying it could be an opportunity for NADAC to do the same, probably at a much lower budget level. It would be a lot to take on for sure.
