Yes casual Royals fans, it would be absolutely terrible to trade Greinke's next two years (when we will have no chance at the postseason) for a trade package of young studs that we will control for 6+ years and will arrive in KC at the same time all of our other top prospects come up.
Trading Greinke near his peak value with 2 years remaining on his contract is exactly the correct move. Our window is 2013-2018, when Moose, Hosmer, Myers, Montgomery, Dwyer, Lamb, Colon, etc. all arrive. Adding 3-4 stud prospects to this stable to go for it all during this window is what we need to do.
