So what were they watching on the monitors? The officials watched something, and the TV broadcast didn't show what was on the monitor so I suppose they could have been checking flight times or maybe porn. But they changed the call after going to the scorer's table and seemingly watching something on monitors.
My guess is they were watching the play, since they reversed their call, and maybe without a formal "replay."
The never went to the monitors…they huddled and discussed it in the floor.
