Football is an art not a science.

Goal Line Technology such as GoalRef is instantaneous. The project intended only for a signal to be immediately sent to the system it's hooked up to and into the referees watches. Upon receiving this signal (all this happening in a split second), the referee would know for sure the ball crossed the line. HawkEye also takes a literal split second, unlike your typical video review. While HawkEye requires a request to spit out its "Goal" or "No Goal" answer, it is still lightning fast. A coaches appeals system to the 4th official would work nicely here. Both of these methods are in the final levels of testing for use in professional play. I am a referee myself. I understand it's an art. This debate is over GOAL LINE technology though. Not "fix every call the players don't agree with" technology. *No* Article wrote:Do we want to stop the game for every debatable decision." *No* Article wrote:"Was it a handball, did the defender play the ball or take out the man, which way should the throw in be awarded, should it be a corner or a goal kick, was the forward marginally offside or not etc..." These are all subject to the interpretation of the official. Do we want to stop the game for every debatable decision? Of course not! Flow of the game. But is the ball going over the line a debatable decision? No. There is no gray area. It is either all the way over the line or it is not. There is LITERALLY a line. Calls on the field: Interpretation of the referee. Examples: "Was there intent?" "Will the player gain advantage?" "Was that shoulder to shoulder contact or did he push off with force with his hand to send the player down?" BUT, with all this in mind: Ball going over a line (ESPECIALLY a goal line) is this or that. It did go over or it didnt. White team did earn that goal, red keeper did fail to save that goal. OR. White team did not earn that game winner, good save by the red keeper. Goal line calls are this or that. Because the human eye is sometimes incapable of seeing it, this is one area where technology can improve our skills. Are we asking the technology to make the calls on the field for us? No. They are to the interpretation of the official, as always. But over the line or not? There is no interpretation. It is, or is not.
