I like this idea. There will never be 100% agreement on calls made on the field, as is witnessed every Saturday and Sunday when expert pundits try to tell us which way a review will go. The amount of times these experts are wrong just shows that there is so much subjectivity, and getting an explanation as the the "why" of some calls would be refreshing. What did they see? What made them throw/not throw the flag? Yes, there are many who would still yell and complain just as loudly as ever, but it would be interesting and insightful for everyone else.
