Lowell is a great teammate, and he is a dead pull hitter, and I think he'll love to take aim at the Monster. He made 7 errors last year, and would actually be an upgrade at 3rd defensively. Kevin Youkilis would move to 1st base.
Also Burnett, and Romero would be a major upgrade in the postseason. Imagine that rotation in the postseason of Schilling, Wells (one of the best big game pitchers) Burnett, and Clement, that's pretty damn good.
