Semi-die-hard Red Sox fan here. It looks like the Sox have shored up their bullpen and strengthened the starting rotation. They also made a great decision in letting Edgar Renteria go, maybe there'll be a few less errors at SS this year. Actually, they've revamped the entire infield, which needed to happen. They also kept Manny (for the moment), and David Ortiz, so the hitting will continue.
Oh, and I have to add...Johnny Who? Coco Crisp in center now, meaning more speed, better arm, and not much loss in the lead-off spot, if any.
