The Reds pen is actually pretty decent this year. It would hard to be worse than last year, of course.
The other problem is that it is coming at the expense of the rotation because they shifted Iglesias and Lorenzen. Which I think they had to do because of health/endurance issues but now their rebuilding SP core looks a lot worse.
I think Reed will be an okay mid- to backend starter. Rookie Davis will probably not be anything. If DeSclafini can stay healthy, that could be another mid-rotation guy. Who knows with Stephenson. If it pans out, Stephenson, Desclafini, Reed could be a solid 1-2-3. Or you might end up with one #4 starter out of the whole bunch.
