On the surface, this may seem like a good idea, but I’ve seen plenty of time where, despite all the camera angles, a player’s body was blocking a view of the ball/puck/frisbee/whatever and replay was basically useless. In this instances, you really need a “disinterested” third party on the field to make a call. It’s why the replay has to be irrefutable to overturn the call on the field. Also, it’s been awhile, but the NFL used to review just about every play and it was annoying. Games lasted way too long, and it was really hard for teams to maintain any momentum after a big play. Fans actually applauded when they significantly cut back on how much they would review. Since then, they’ve been incrementally bringing it back into the games and I think they’re almost back to it being too much.

Bad calls are a part of sports. They suck, but it’s a random bit of chaos that creates a Bad Guy for all the fans.
