Keep in mind that Win Shares is somewhat a measure of opportunity, so that could figure in. If Biggio saw more flyballs, then he'd get more credit for his defense than a fielder who plays for a team whose pitchers throw alot of groundballs.
Another note, Hidalgo's fielding is rated higher than Biggio's, but Biggio played 100 more innings in the field.
While we're on the awards topic, the HOF is giving fans the opportunity to pick broadcasters to appear on the ballot next year. Voters can cast their ballots here.
