NFL admits it got flag wrong that negated A.J. Green TD

[*rfaulk34*]

The refs need to be off the field, save one. With technology today, they should be able to watch from a monitor and when there's a penalty, simply call it out (through a headset of course) to the official on the field to throw a flag. You have announcers, production crew and many others with a much better vantage point, yet you keep older, slower officials with a bad angle on the field to mess up way too much. 

EDIT: Well, one wouldn't be enough. Spotting the ball and out of bounds plays. You could get by with 3 or 4, but there should still be officials watching monitors for penalties.
