Re: Why we need computers calling balls and strikes
If there was an automated system that calls balls and strikes, the only reason an umpire would need to "control" anything was between two team's drama. For the life of me, I can't understand why only in baseball are the umpires/officials allowed to instigate yelling matches with the competitors on the field and vice versa. NFL has a very good reputation between players/coaches and umpires and only a few times do I remember any conflict on the field.
If I had my druthers, I'd:
A. Automate balls and strikes
B. Enforce a remote instant replay system like NHL to review all plays meting replay criteria
C. Rather than throwing a player out of a game, reward an out to the opposite team.
I like C only if an automated system is in place as well as remote replay since the player no longer should have the need to yell at an umpire for balls/strikes, or missed plays a remote replay official could correct. Any yelling at an umpire is surely sour grapes and needs to be penalized like in football.
