By 2017? Really? First off, Pedroia won't get $20mm a year. He'll get around $14-16mm a year. Lester will get his 5/$100mm.
I don't know where you get these numbers, but the Sox don't overpay like the Yankees (Jeter, ARod, Mo). They pay market value.
The Sox will resign Lester and Pedroia, that's about it. They won't give Buch 5 years at 32 years old, which he will get elsewhere, and the Sox will let him walk.
Theo will have Gonzo, Crawford, Lester, and Pedroia locked up for $15-20mm per season. How is that much different than next year with Gonzo, Crawford, Beckett, and Lackey?
You're kind of a drama queen.
