The Royals should really take chances on signing low risk, high reward guys like Xavier Nady and Justin Duchscherer and I will explain why. Xavier Nady is coming off TJ surgery so he will come cheap but the man does have pop and is a good OFer. But why I think the Royals would be a good fit for him is that the Royals have Jose Guillen who also had TJ surgery a few years ago so Guillen could help Nady on his road to recovery. Plus the Royals need an OF/DH type. Royals could push DeJesus back to CF and have an OF of Nady, DeJesus and Guillen which would be a great improvement.
Duchscherer is intriguing because he too is coming back from elbow surgery but didn't not come back late last season from suffering depression, something Greinke had bouts with. Greinke could be a huge deal of motivation for Duchscherer and get him back to his 2008 form. Who better to help him than the 2009 Cy Young winner?
These are two low risk free agents the Royals could really benefit from if they return to their former selves. They have players now who have been what they have gone through and Nady and Duke could really benefit from being around these players. If I was Dayton Moore, I would pick these two up.
