Even if you don't agree regarding Lohse/Teheran, Wren still ignored the depth problem. Saying Huddy should've been ANYTHING is just being silly. You can't do that when you are building a team for a 162-game season.
Wren could have acquired someone at the deadline thats fine. But before the season like you are advocating makes no sense. There was no room in the starting rotation to add someone.
You aren't getting a frontline guy to be in the AAA rotation and the guys that came up during the year actually did a good job. But, thats why they are willing to go to AAA because they aren't big time pitchers so whats the difference for now?
