It may be speculation, but it isn't idle. There is no definitive way to know it, but that doesn't make it unworthy of exploring. Numbers are a good guide, not a be all and end all. If there's no definitive way of knowing, why bother exploring it? If there's no answer, there's no use for the question. What are you going to do? Have Bruce Miles ask Prior if he is afraid to pitch to Barrett? Please, it's a waste of time. You're not much on philosophy, are you? When you are using it as an arguement against a player without any proof that it is actually true I do have a bit of a problem with it. Have you ever heard one of the Cubs pitchers in the last two years say that they don't like to throw to Michael or that his defensive abilities sometimes worries them and decreases their effectiveness? I asked what if a pitching staff doesn't like to throw to a catcher even though he can hit. I'll change it to read that. Now, what would you do as a GM? I never said the Cub pitchers didn't like throwing to Barrett. If you are a gm, and you know for a fact that your pitchers hate throwing to your catcher, you replace him. If the catcher is so bad that the pitchers are complaining about him being behind the plate, then you either have the whiniest pitching staff ever, or you have a catcher who is complete garabge. If your catcher is that bad behind the plate, chances are his overall contribution is going to be less than league average.
