That’s the problem, the initial spot was way off causing the refs to say he was short, so the ****** views of the play have to be used to overturn a terrible spot. Had the initial spot been even remotely accurate the on field call could have gone the other way, which then would be too close to overturn that call. This was always going to be the problem with replay. It sucks and is just as inaccurate and as biased as before.
Sometimes the angle and other players during the play make it impossible to tell but we want them to fix the call anyway. With the Tech we have why doesn't the ball have some chip installed so the first down markers detect if it made the line to gain or not? if nothing else, the sidelines and end zone should be able to be monitored by better than a pylon camera.
