The Red Sox can't afford to give long contracts to guys like Jackson/Lohse/Dempster who will fail hard in the AL East. The number of available starting pitching has significantly dried up already. The list gets longer every day:
Burhle,
Josh Johnson,
Guthrie,
Ervin Santana,
Hanson,
Haren
Kuroda,
Peavy
Baker,
Pettite
