I am a complete luddite with respect to reviewing referee decisions. Unless corrupt, we know every referee intends to make correct calls. Players make mistakes all the time in games; perhaps we should let players re-take penalties that aren't on frame, because surely they intended to at least put their shot on goal. The fallibility of humans is where drama is born. It is too bad so many of us fans don't consider referees human. I am not such a luddite that I think allowing communication to occur via headset is wrong, but I absolutely think it is wrong to replace on the field, human judgement with technology. Hmmmm...I must be achieving the curmudgeonly state I always dreamed of in my youth.
