HaverDad:
Let me state up front that I am not in favor of any instant replay.
I'm not sure that the 'wild card' change is the same as a change allowing 'instant replay'.
I accept your point that any change will impact the 'tradition' and 'integrity' of the game and as such these proposed changes should be weighed and considered very carefully.
Any movement towards 'instant replay',in my mind,is a move towards fundamentally changing the game. Umpire decisions are more difficult to accept than game decisions (W/L) especially if it is thought that the game decision was improperly influenced by the umpire. Perceived wrong decisions by an umpire are not popular and it seems an easy fix would be to scoot them increasingly out of the picture.
Its kind of like an environmental battle where you're asked to 'hug a tree' or 'cut a tree'. Without much thought people will almost always go for the hug thinking they have done something good without realizing the effect that decision has on a far wider scope. Imagine a world where no tree was ever cut...aluminum bat anyone?
Those of us 'inside baseball' can reasonably argue for or against 'instant replay' from an informed perspective but if you were to put the question out at large to the general population they most likely would ask themselves 'what's the harm? Every other sport seems to have it'.
Because of this we, the baseball community, must be vigilant when it comes to changing baseball.
I'm digging in and saying no to any and all 'instant replay'.
And by the way ...hug a kid and not a tree!!! IMHO!
