That really helps to make my point. I want to see the best teams in the playoffs, not the team with the one best pitcher. This (STUPID) one game wild card playoff can match a team with 100+ wins against a team with 90 wins and one outstanding pitcher in a winner-take-all situation. And to make that situation even more ridiculous, the those two teams don't have a chance to set their rotation so the two best pitchers will face one another.
I've long been a fan of Crash Davis. He may be the one who first made me realize what was said in your post, that .050 difference in BA is one hit a week. Maybe that's why I still champion keeping JBJ in CF even if he's not hitting. I'm confident that he takes away at least that one 'extra' hit a week from the opposing teams. Maybe not one every week, but the next week he may take away two!
