I know Lackey has been in a rut this year, but to be honest with you, if Buchholz isn't available for the post season, we've got a rotation of:
Beckett (3.07 Postseason ERA, 93.2 IP)
Lester (2.57 PS ERA, 42 IP)
Lackey (3.12 PS ERA, 78 IP)
Combine that with our offense, and I feel very confident that we can get it done.
