Their pitchers depend on that defense a LOT...I think this actually could hurt them quite a bit...also because the middle infield rotation was working well because of rest and matchups...if Ryan, Miles et al are playing every day, as opposed to just when matchups favor them, I think you'll see drop offs in their production. They may depend on that defense a lot, but how many chances is the replacement 3B actually going to get a game that they won't be able to make but that Rolen wouldn't have made? The difference between a great fielder and an average one isn't all that much. In the short term, it probably won't even show itself. I think it may...especially when coupled with forcing Miles, Ryan, and Eckstein to play everyday. Ryan KILLS lefties, but doesnt' hit right handers very well at all (.255/.300)...he used to sit those games...now he starts every day...Miles was getting a day or two off a week...now he's got to start every day... They dont' really have any solid system replacements....if this results in just a one game difference down the stretch that could be a lot in this race.
