I am not the only person on this site that has said, Julien, and few others, have been given gift of not listed as an error even though they screwed up; Although, that also gives some batters a gift in there Batting Average.
For a point:
Ozzie Smith, one of the best Short Stops that ever played the game; in the 5 years he had Twenty of more errors, his precentage ranked from .970-.974, while also in each of those seasons he played more than 130 games.
So, while errors are an obvious failure, the ability to turn a double play counts heavily in defense numbers and Julien, is slow at turning double plays.
