So in light of the whole Jim Joyce deal, I have come up with a solution to the whole "Instant replay would slow down the game!! Rabble rabble!" debate.
This argument has already been proven FALSE.
MLB has recently (last year I think) implemented instant replay for questionable home runs. If there is a questionable home run, they immediately look at the replay, and correct/uphold the call. It takes 1 minute tops.
In the past, this is what would happen:
-Manager would come out and argue for a few minutes.
-Crew chief would gather up the umps, and discuss for several minutes with each other what they THOUGHT they saw.
-Crew chief would change the call.
-Then the OTHER teams manager would come out, and argue for another several minutes.
So, which way is faster? Exactly.
There should be instant replay for everything except for balls and strikes, and balks. Similar to the NFL, there would be a challenge system, in which you get so many challenges per game.
Now, with that in place, there is no longer a need for managers to leave the dugout and argue calls. If you leave the dugout, its an automatic ejection and two week suspension without pay.
This gets the call right AND speeds up the game. Problem solved.
Your welcome.
