I've said many times since the AAF introduced the concept of the sky judge that the NFL needed to implement it immediately.
It's an active view, not just a review.
The sky judge can view and re-view plays multiple times right up until the next snap.
He would only need to stop the game if he sees a problem.
When the on-field refs throw a flag, the sky judge could review a play about 6 times before the Ref announces the call.
If they made the Sky Judge the head of the crew, it would have the best outcome.
The head of each crew is often the oldest ref in the crew anyway. Just make that guy the sky judge.
If they could put him in a little booth on the sideline that would be even better. Put windows in the booth and have it where the cameras can show the sky judge like they show the on field ref when he announces penalties.
Having an on-field ref come over and watch reviews on a tablet like they do now is the dumbest idea ever.
The sky judge could see 6 reviews before the on-field ref sees the 1st one.
