That's why I advocate having on field replay the way the NFL does it, not this booth review business. The NFL typically does things right, and they have replay right. I even like the reviewing of all scoring plays they've started this year in the booth, followed by an on field review.
I just don't like a guy in a box making the official call for the on field ref. Sure let a guy in the booth handle the buzzing down to let the ref know to review a play, but then let that guy go to a booth and make the call.
The other thing I think it would fix are these instances when the official makes a call because he thinks he knows what happened. The Bumphis play was a good example. The ruling on the field was an interception. To overturn that, the rule says you have to have indisputable video evidence to overturn the call. It then becomes like a court of law. If you can't convict with 100% confidence, and you can't give a screen shot that shows the exact reason why, the call stands as called on the field. The replay officials only have the same angles they show on the television broadcast. On the Bumphis play, there was no angle that showed definitively that the nose of the ball touched the ground. It appeared from one angle that the ball likely touched the ground as Bumphis went to the ground, but at no point, that I could see, did the video show conclusive evidence that the ball hit the ground.
The announcers were even saying that the play would stand as called. All you could tell from the video is that Bumphis never had full control, and you couldn't see an angle where the ball touched green grass, but the replay officials interpreted what they thought happened. That, to me, wouldn't happen nearly as much with an on field official.
