It was silly to blame the "replacement refs".
The NFL's rules state that a ruling of simultaneous catch isn't reviewable, which is why there was no chance of an overturned call there.
Watch that play full-speed as it happened and try to make sense of it. It's really, really hard. We get to see it in slo-mo over and over and even then there's still debate. The refs get to make one call on the field in that instance. I think they could review a called interception to determine if it was, in fact, a simultaneous catch, but keep in mind the burden of proof needed to overturn a play. If a ref calls it a pick thinking a review will sort it out, it puts the offense at a huge disadvantage. They have to call it the best they can, right there, right then. If the NFL simply allowed for a review of that type of play, perhaps a final decision could've been made.
Yet we blame the refs who have to react instantaneously to a mob of people playing flyer's up with multiple people having hands on the ball.
