With the season basically over, I still think some good can come out of the rest of the year. Here are some things I'd like to see happen (I know some are very unrealistic):
A) Parra develop some consistency. He needs to be a #2/3 type guy next year for the Brewers to have a chance. Or, at the very worst, a good 2nd half of the year will boost his trade value for the offseason.
B) Villanueva develop into a reliable SP. I know, at this point in time it looks highly unlikely. But it wasn't too long ago that he was seen as a future member of the rotation. He's shown he can pitch at the ML level effectively, and his repertoire is definitely starter-worthy. If he could be a reliable SP next year it would be huge.
C) McGehee gets a lot of PT and shows whether he's for real or not. Even if he fades, this helps the Brewers by letting them know what they've got in him for next year.
D) Hardy produce, to boost his trade value for the offseason.
So, if those things happen, or at least a few of them do, to some extent, I think the rest of the season won't be a waste.
