I think replay is a necessary evil. The best fix to replay I've heard came from a poster who hasn't been around here for a few years. All replay reviews should be done at game speed, no slo-mo replays. The blatantly bad calls will get overturned and folks would have to learn to live with the marginal ones. As it stands now there are tons of Zapruder-ish reviews where nobody agrees with the final call anyway. BTW, I don't expect this idea would ever get any traction.
