Neither Werth nor Crawford is gonna command a 20 mill salary IMO. 15 million probably gets you Soriano plus a lefty, but i think the Sox should also explore bringing Bill Hall back, since he was so productive this year. Also, you need to consider that the Sox could, if they deemed it necessary (and it certainly seems necessary) increase payroll for next season.
Dipre's ideal 25 man roster:
C: V-Mart, Tek.
IF: Youk, Pedey, Beltre, Scutaro, Lowrie.
OF: Drew, Werth, Cameron, Ellsbury.
Super-sub: Bill Hall.
DH: Ortiz/Dunn.
SP: Lester, Buch, Lackey, Beckett, Dice-K.
RP: Papelbon, Bard, Soriano, Scott Downs, Okajima (now a Loogy), Atchison, JJ Putz, Dustin Richardson.
*Ideal is bolded because it's very diffuclt that happens.
