Why not swap Murton for Nady? Murton will be the overall better hitter but Nady will probably have more pop. Nady is an excellent RF with a cannon, while Murton is an average outfielder with a decent arm, who is more suited to LF. Since Soriano is going to be there for, well, the next 7 years, Murton looks like he has no position on the Cubs at the moment. Murton/Marshall and filler for Nady would be cool with me.
