Clark Fosler's article on Royals Authority outlining why he thinks the Royals should trade Greinke and what he thinks they could expect in return:
After reading through the Cliff Lee threads last night, I'm of the opinion we should push hard for Greinke instead. He's younger than Lee (26 to 31), cheaper (7.5 to 9) and we'd control him for longer (2.5 years to .5 years). He's also the better pitcher IMO. All that being said, he' probably cost us more in terms of talent as well.
I'd personally be willing to part with any 4 players in our Minor League system and Bailey from the Major League squad.
Assuming he's made available, I'm thinking a package of Bailey, Wood, Maloney, Mesoraco and Francisco gets it done.
