I dislike that as well. Thing is, last yr we had the relievers to handle it. As poor as Farnsworth looked, he really only hurt us twice taking over for Mo. And for the most part, our MR was good enough to essentially wait it out until the offense piled on (thanks ARod) enough to put the game out of reach.
This is in part why I am harping on a team like the sox finishing the pen. You have what looks to be a pretty damn good rotation, one that has the POTENTIAL to be the best in the league. You have an offense that, while it isnt the 2003-2005 version, is still going to score a ton of runs. This is going to translate into a lot of leads getting handed over to your pen. But I have NO faith in that pen. Okajima is flat out unproven over here, and other than a plus curve, he screams lefty specialist in scouting report. Timlin exploded for the last 2-3 months. Donnelly has some very poor trends as you said. Romero was awful last yr. The kids proved that they are not ready. If you are going to have a team that will inherently have a ton of leads, you should have a bullpen built to hold onto them. If you get a closer, a good one, not some retread, then the pen goes from awful to serviceable. A good closer to a team like Boston is something that should be mandatory, unlike to teams like Pittsburgh or TB who may not have enough leads to keep their closers busy.
