Obviously, both positions are important defensively. In most cases I would value defense at SS a little more than in CF. Primarily, because there seems to be more of an abundence of decent fielding CF who can at least hit a little. Many times at SS, it seems to be feast or famine, either great defense and no bat, or a good bat and bad defense, except for your rare exceptions such as ARod, Rollins, ...Jeter. Also, I feel that while CF is a tough position to field, I do not believe it is the toughest OF spot to play at Wrigley. That honor would go to RF, due to the contours of the wall and whatnot. That being said, I would like to sign Fukudome for RF, put Pie in CF, and somehow still get Murton a decent number of AB's against LHP. I would also like us to bring in a better bat at SS, but I just don't see that happening.
