Lackey replaces DiceK, Dempster replaces Beckett. Lateral moves for the most part, possibly some minus moves depending on how they adjust from injury/new league. I thought Dempster was a good signing, but I said from day 1, the sox needed to add 2, 200IP starters. They got one. Marcum, if healthy, was the other. If you get innings from your starters are quality production, then your improved pen could stay lockdown and you'll see a rise in the standings. If Lackey shits the bed, Dempster retracts into his shell, Doubront gets hurt due to his IP rise, Buch takes his yearly sabbatical to the DL or Lester continues his mediocrity then your pen gets torched. When one of the above misses a lot of time, your #6 option is a rookie or a retread that will mutilate your pen further. There was a reason why the sox pen in 2004 was so good, even though the only real name out there was Foulke. Because your starters regularly gave 6-7IP and your pen was rested.
