This series is much better done than most national media looks at offseason planning (although unfortunately it's a pay article). Heck, it almost could have been written by someone here at Twinkie Town!
It suggests the Twins already have a "true ace"--Liriano--and as far as the need for a "second ace" to back him up:
"Greinke’s 3.70 SIERA, as well as his walk and strikeout rates, were a dead ringer for another pitcher the Twins already have: Scott Baker. Sure, Greinke is probably a better pitcher than Baker, but given the $6.5 million difference in their salaries I wouldn’t trade Baker for him straight up, let alone put together a package of Delmon Young (of whom I’m no fan), Kevin Slowey, and top prospect Aaron Hicks, the rumored starting point for negotiations regarding Greinke."
Instead, the article suggests targeting an undervalued mid-rotation type like James Shields to instead bump Blackburn off the back of the rotation.
I also liked this part:
"Mission Statement: Win enough games to make the playoffs, then bring along enough talent to beat the Yankees, Red Sox, Angels, or whatever other expensive coastal show pony we meet there, and in doing so play deep enough into October to distract the honest, hard-working citizens of Minnesota from their cringe-inducing local football teams."
