boston's done all right with some pretty shaky defense up the middle. And Atlanta has done well being solid there. they're also 3rd in the NL in runs and 6th in the NL in era. are you saying their defense at c, 2b, ss and cf is a bigger reason for their success than their hitting and pitching? seattle has the fewest errors in mlb...they must be winning their division by 25 games. Again with extremes. It's a balance that needs to be addressed and if you tell me that if you have two exact teams only one has worse defensive players up the middle that that team would be better? Also, errors are objective...score keepers are not reliable in what I would look at. Also, If you have pitchers giving up missles it doesn't matter who have out there. Balance is needed..good balance and solid up the middle Defense is always a good place to start. Look at the dominate 70 Red teams...yeah they could hit but they were also awesome up the middle. of course you'd rather have the team that's solid defensively up the middle. but no team is good-great at everything...and, for me, in a fantasy draft of team skills, good d up the middle would be pretty low on my draft board. if you can show me a replacement for barrett that is a perfect balance of offense and defense, maybe i'd want him. but i don't know who that is.
