I'm all for officials and the NFL wanting to get the call right on the field. But stopping play for 3-4 minutes at a time so the ref can jog over to a screen, put on a headset, watch the replays, then jog back and make an announcement is asinine in the year 2023. Have an extra official or two in a booth watching replays at the same speed as us at-home viewers, and give him a microphone and an earpiece to be able to talk to the ref. Have him hooked into the production crews camera feeds with an Xbox controller so he can pause, replay, rewind, flip between cameras and angles. If the sky judge sees something, he radios down to the ref to hold up a sec (if more review is needed) while he and partner rewind and replay, change angles, etc. and then he calls down with a simple "nope that's incomplete, 3rd down" and the ref calls it out and away we go. 15 seconds for review is all that's needed in a majority of cases.
There's a friggin microchip in every football. Have the sky judge sitting with the technology and seeing where the ball made it to. He radios to the ref to spot the ball at the X yard line. Started at the 27, now the chip says the ball is at the 37, first down lets keep it moving. So many plays are then spotted by a 50 year old man running in from a sideline and spotting the ball where he thinks it got to, but of course he couldn't see through 5 bodies to see where the ball actually got stopped. No reason in the world we need to sticks with a chain on them anymore.
USE THE TECHNOLOGY.
