Personally, I'd rather just call up Brett Phillips. Sure, he swings a wet noodle of a bat, but so does everyone else on this team. The guy is FUN. He's a fan favorite in every other city, he plays great defense, and seems like a fun teammate for others to be around.
We aren't winning games. We aren't going to score runs. You want veteran leadership to change the culture of this team? Brett Phillips can have a much bigger impact on this team than any other journeyman we think can be a bandaid for this team.
