This is the risk they get hurt or greatly underperform?
If so, it amounts to losing about 1.25 starters. (Maybe 40-42 GS) I might project more like 50-55 GS.
In house solutions?
IMO, Houck should start the year in the pen and stay there, but I'm not sure how Brez & Co. view him. He ended the season healthy and pitching. If you put him at 50% and as a SP, he could start 15 games.
Crawford should remain a starter, IMO. He was ready to start the last game in AAA, but it was cancelled. Maybe count him as 60%. That's 12 GS.
Oviedo is hard to project, but he was healthy, too and is a SP'er. How about 50% and 15 GS.
If all three are starters, maye they give 42+ GS with a possibility of 90 GS if 100% healthy all year long.
I doubt Brez adds a stud pitcher. I don't think he planned on Suarez, this year, and Crochet can be viewed as Gray's replacement.
The scary part is Paez is the only AAA guy on the 40. Wehunt is Rule 5 and may be added. Holobetz and Ziehl could be added, when and if needed, but none of these guys wow me at all.
I could see Brez adding another Oviedo type, but maybe he gets lucky and adds another Bennett type.
