But if replay takes the pressure off the refs, they should then defer to replay, and you do that by not whistling the play dead if there's a fumble, or ruling it a TD so that replay can decide if it is one or not.
As soon as those refs were conferring on whether or not he was in bounds, and it was taking so much time to figure out if either saw it, the default should be to go with TD because of replay. It's a luxury they have.
Very much like the Harden dunk that clearly went through the hoop once, but not the second time. The refs didn't see the net slingshot the ball back above the rim and disallowed the points. They claimed the play was not reviewable. I can understand why Powersthatbe don't wish to make judgement calls reviewable, but if a central tenet of replay is not to correct obvious wrongs, there is no reason for replay at all.
They conferred on "unreviewable" plays for longer than what it would take to actually review the darned thing.
Another example is in hockey. The puck can be in a team's defensive zone for, in hockey terms, forever, but only because the puck was literally two water droplets behind a skate blade 83 feet away 70 seconds earlier, the goal is disallowed.
Back to football: Before the Megatron disallowed-touchdown a few years ago, there was little ambiguity in the definition of a catch (Two feet inbounds and control of the ball.). Only after they are "allowed" to review it and slow it down to less than 1/36 of a second, does unreasonable doubt creep in.
Arbitrary replay rules are making sports unwatchable.
