As you all know, Choo's defense in CF is terrible and it is actually the worst(-14.3) among qualified MLB outfielders according to Fangraphs' UZR(Although I don't believe in defensive metrics personally). But Choo's defense has not been a problem at all during the season.

I can't remember a single instance in which Choo's defense had a decisive effect on a game except for the one against Cards in early April or cost us a game.
