So many people seem to be incapable of understanding that the referee's perspective was different than their own.I think too much credit is given to "Higher Authority", I believe in Occam's razor, that is the sheer incompetence of the refs. Some of it isnt their fault, the game is just too fast in addition to the multitude of outcomes that can occur during a single play. But a lot is their fault. I do believe that Puka has a point, like in baseball where the umpires like to be known with audacious K calls and throwing out players/managers at the drop of the hat, these refs/umpires on national tv like to be seen. And just my .02, but I think a lot of times they are determining a penalty prior to a play, like watching a tight matchup and thinking "next time I'm throwing a flag".
The gambling angle is silly IMO
One of the things I liked about the World Cup soccer matches was the referee's view cameras. Put a high def cam in the brim of NFL ref hats so we can see what they saw in real time. A lot of the conspiracy theories will evaporate. I always thought the non-PI call in the 2018 NFC Championship was probably very defensible as a bang-bang call from that referee's perspective in real time.
I think anytime you have two or more refs looking at the same play where not all throw flags, there should be a short conference. If they disagree then someone with quick video analysis should be able to come into their earpiece with advice.
