@Region Philbis,
There's so much truth there.
Pedroia is the spark plug in hitting and fielding and in so many ways, I can't overstate it.
However, Crawford couldn't possibly hit any worse than he is so let's assume that 'cause he's hit very well throughout his career, that he'll snap out of his slump. Along with that, Ortiz's power hitting and reasonable (.280+ at least 30 more HR and over 100 EBI) is/are essential, too.
Oh, and Ellsbury to be solid in the field and leadoff are a big plus. I'd love for him to steal 30 bases again, but I'm not a glutton. It'd just make them such a worrisome lineup and make the other teams toss the ball away trying to get him out.
That leaves the essential position of defensive catcher to 'Tek to and hope her comes around. the need for a top defensive catcher, a solid but not flashy SS, and the others need to do their thing to make the Sawx contendahs in October.
