Re: Reds aquire lefty, Jeremy Affeldt ...
Better than a sharp stick in the eye. I imagine he starts the season in the rotation. Lowish K/9, highish BB/9. He's basically a mid-level projection of what Bailey might be this year. ERA floating around 5 depending on his luck. For only 1 year and $3M guaranteed, not a bad idea.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
