IMO, this team has plenty of defense, and we lack tehreof in offense and pitching. Though the bullpen is a top priority, the problem enlies almost fully in the pen, and acquiring 1 good starter.
The offense is basically Papi and Manny, with no otehr decent threat that can be respected as close as the two mentioned. If we can get Aramis Ramirez, and can trade Lowell for a decent arm for the pen, we kill 2 birds with one stone, getting a deepball threat and a (hopefully) reliable arm. Coco is an auto upgrade from himself last year so tehre's a solid leadoff, letting us move Youk into the second spot where he can be very dangerous. If we sign Lugo as spoken of, we have a solid lineup again and can focus on pitching for the rest of the off-season.

This of-seaosn could very right or very wrong. Doing the mentioned would be a good step IMO, maybe shipping Lowell and otehrs to SD for Linebrink (who would be a very solid arm). The rest I can't see any obvious solutons.
