Please reread what you wrote. How can Kike be a terrible decision when you agree that Story, Chang, Reyes, and Mondesi were injured and Hamilton proved to be problematical? Also, his overall WAR is just -0.5. That's pretty lousy, but my understanding is that it means he would cost the Sox 1/2 of a loss more than an average player would--in 79 games played.
To me the SS situation is not unlike the catcher situation with McGuire gone. We've just watched our 2d straight lousy backup, which is why Wong is catching so many games.
So too the rotation.
