have you auto-calced or done soemthing to maintain your LTM?
- know baseline for various, more basic defensive stats. like: fielding pct / of assists / double players etc...
if you auto-calced, no worries on that stuff. if you didn't, double check they(stats, offense/defense etc) are lined up with whatever era you are in or customizations you want.
if you know the league is roughly where it should be, you can move on to deducing if it's your park or your roster strategy or whatever. from the foundation to more specific things avoids compiling problems with adjustments that weren't needed.
as far as the park, find players that played in their prime years with your team and another team... take it as a grain of salt, though. pay more attention to the stats the require smaller sample sizes.

use your own source for those #'s. they can't be much different, either way.
i like how they use BF... much smarter.
edit: my teams play in a more neutral park, but i've had some good defensive teams not look so good with certain defensive metrics.
if i recall they normally were ~.710ish defensive eff, but then a couple years with essentially the same team it was .680's and pretty average, slightly under league average. i had good defensive rated players... trust in that.
not just he overall for the position - look at the breakdown yourself... i value some thigns a bit differently than the AI. i don't think a 100% optimum one-size-fits-all solution exists... you can definitely find a better way to assess it relative to your league's setup (very large # of variations used, not just possible).
so, in a modern-like league if you have some guys that are 60+/100 defense but their range is ~50/100 give or take, they probably aren't as good as what they look like by that green defensive rating... maybe in an era of really low fielding percentage that view might change drastically. in that situation, the sure-handed guy probably looks even better than a 60+/100.
(probably more in reference to a more important defensive position, than say 1b or corner OF.. a sure handed 1b is all you need, but their ratings generally reflect that setniment well, in my experience -- eitehr way make common sense adjustments per position and leauge environment)
