INTRO PARAGRAPH. SOMETHING ABOUT IT BEING FUN TO CELEBRATE AWFULNESS, LIKE 2010-2013.
First, some disclaimers:
1) I know some of the names of which you are thinking. But those guys probably didn't get enough ABs to qualify for the batting title, or innings pitched to qualify as a pitcher. I'm looking for worst start-to-finish, honest-to-God everyday player in Astros history. So you're not going to see Carlos Gomez, Jon Singleton, Brett Wallace, Jordan Schafer, etc. They didn't play enough to qualify.
2) I'm using FanGraphs' version of WAR because it's easier to sort. I like easy.
