They're still going to use the sticks and chain as a backup.

I would love to see it. Take away any potential for error possible. The technology is there, they just need to use it.

We really got shafted in the Buffalo game with spots. It was crazy.

If they can fix that I'm all in. For some reason I fully expect this roll out to start with a complete and immediate failure. Hopefully they've tightened all the screws on this process already...

I could not agree more, it is maddening!

It looked like on our final drive in overtime that we made the first down twice on 3rd down. But, they marked it short. Twice we had to make a 4th down or we lose the SB. Maybe if this is in place they call down to the refs and tell them it was a 1st down.

Words like "Optical Tracking" sound like they're playing around with computer vision, AKA convolutional neural networks and drawing bounding boxes. Using that kind of technique you wouldn't need sensors you'd use a model that's been trained on tens of thousands of hours of video and you measure the probability of false alarm and probability of detection. Get the PD up to 99% and the PFA down and then you can have some level of confidence that you're outperforming the human.
