Didn't we have this 1990 conversation before? SS A aka Cal Ripken (a guy who made a career playing every inning of every game) made 3 errors... for the season. SS B aka Ozzie Guillen made 17 Es -- and won the Gold Glove. But, to your point: CR 435 assists, 242 put-outs; OG 474 assists, 252 put-outs.
Obviously those stats show Oz accounted for more outs, and they might show more range... but Ripken was noted for his first step -- before contact -- knowing the hitters and pitchers and anticipating locations of batted balls. Is it possible Guillen had more chances because his pitching staff pitched to more contact, induced more ground balls, and kept the ball in the infield more than Baltimore's?
Upon review of '90 team pitching stats, the O's were second-to-last in the AL in strikeouts, while Chicago was better than league average. However, the fact that the White Sox won 94 games and the O's only 76 may mean that Baltimore's pitching just gave up more hard hits out of the infield. The Orioles gave up the second-most home runs; the ChiSox gave up the second-least...
