Who would you sign instead? There were some options, but most of them would see serious ERA bumps in Fenway. Here are the options from last year.
Shields 4/80. I still think he was a great option, but not exactly cheaper.
Brandon Mccarthy 4/48. (He is already hurt this year).
Ervin Santana 4/55. Might not be a terrible choice, but he is signed from 32-26, gives up more flyballs, and has a similar ERA.
Liriano 3/39. He can put up some good numbers, but extremely inconsistent. I doubt Red Sox fans would tolerate him.
Jason Hammel 2/18. Career 4.60 ERA in NL parks.
AJ Burnett 1/8. Nope.
Peavy 2/24. I have always been a Peavy fan, but doubt he'd come back after the trade.
Harang 1/6. Awesome start so far, 36 years old and career 4.20 ERA in the NL make it seem like SSS.
Vogelsong. 4.5 NL ERA.
