I know this will open up a huge can of worms, but here goes. Probably not as most people on here seem to favor this. No arguing with umpires as the play would be replayed on the jumbo screen and seen to be correct or faulty. Done deal There were at least 2 plays today that were too close to call even with instant replay, baseball plays are far from done deal. Same thing in teh NFL, its like everyone assumed if you add replay there will never be a bad call ever again. In reality its just not true, pretty much any play in baseball that is close enough for an ump to get wrong is so close that you cant even tell on replay. Plus showing it on the screen will only cause the fans to cheer every call for the home team and boo the others. 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. Um, as Rock would say, "I mean, are you kiddin' me?" Again, today, several "reviewable calls (at first only) and no manager arguements. Manager arguements are pretty rare and certainly do not take any longer than it would to show the replay on the screen several times and have the umpires come together and change a call, plus, any call that got changed based on a replay where it was too close to tell would cause a manager to come out and argue. The umpires would not have the ability to incorrectly change the outcome of the game. One call does not ever effect the outcome of a game. If you think you got screwed out of a run by a call then win the game by more runs. Show me one example where 1 single call actaully changed the outcome of a game. (The brewers -Dbacks fair ball call does not count, that happened in the 7th inning (I think) plus how do you know he wouldnt have hit another double the next pitch?) That blown strike from Dif against the cubs on July 3rd? Well, Ryan Braun had a runner on 2nd in the top of the 9th, get a hit there and we win.... 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 In theory, theory and practice are the same; in practice, they are not. This does not work well in football, it just prolongs the game and wastes time and causes the refs to be even worse. It doesnt work for baseball, there are way too many close calls in a game, pretty soon each manager will want 10 challenges per game and the umps will still be right every time. Also, a strike is not from the arm pits to the knees or whatever it says in the rulebook, it is whatever the umpire decides is a strike.
