I know this will open up a huge can of worms, but here goes. I believe it is time to begin discussion on a ( replay) challenge system on any call made by umpires in a baseball game. I hated the system when they installed it in tennis tournaments. Within 1 week I could see the value of the system and after a few years I cannot believe it was not done sooner. As for the human element, it is over rated in my opinion. I have never watched a sporting event of any kind to see the officials do their thing, and in tennis (with the challenge system) the linesman have become all but invisible in all matches where the system is in place. Players such as John McEnroe terrorized the system with out of control rants in many matches. Today there are no arguments in tennis as the challenge system allows for a player to get his "day in court" and move on with a correct call. I realize that nothing could be done until a new CBA is done with the boys in blue but I would like to see discussion begin now. Advantages: No arguing with umpires as the play would be replayed on the jumbo screen and seen to be correct or faulty. Done deal I believe it would actually shorten the time of game as it could be done quickly on screen and there would be no reason for the manager to go on the field and argue with the umpire for no reason. The umpires would not have the ability to incorrectly change the outcome of the game. Ejections would be a thing of the past as either the player or the ump would be shown to incorrect on screen to all fans Go ahead and shoot me down with this idea but it works very well in all sports where the technology is available..
