On March 31st of this year I published an article Breaking Down The Diamondbacks Rotation. In that article I expressed a lot of concern about how badly the rotation projected. Early in the year we had some debates about which part of the pitching staff was trending worse, the rotation or the bullpen, and clearly the bullpen “won out” in those discussions. However the overall concerns turned out to be correct, and in some cases pretty accurate.
We know that at various points in the season, every one of the “original” starters has been either injured (or suspended).
