Since 2015, the Giants have had the worst outfield in the major leagues. Over the last four and a half seasons, Giants outfielders have amassed just 8.6 wins above replacement according to FanGraphs. In 51 individual seasons by 33 players, Giants outfielders still couldn’t match one typical Mike Trout season. It’s generally unfair to compare anyone to Mike Trout, but this is a horde of players. They ought to be able to outperform what one player generally does in a year even if that player is one of the best players ever.
But they can’t even outperform a faintly good player.
