The Royals have the pieces in place to be very good very soon. I'll go more in depth later, but they've got the power arms in the rotation and the pen, and they "could", emphasize the "could", have the power bats they need in Gordon and Butler, plus the solid, get-on-base by any means necessary players in Teahen and Dejesus. I don't see Guillen as a long term solution, and I don't really think Buck is the guy at catcher. What really needs to happen is for Joey Gathright to emerge as a leadoff hitter. He doesn't need to be all star quality, but he needs to be in that conversation. If that happens, I think the Royals would be wise to trade Dejesus before his production falls (as sadly, I fear it will) and hopefully accumulate a young relief pitcher or a decent starting pitching prospect.
Just my two-cents.
